Need to get a new IP address on Android fast? The quickest, most reliable fix is to switch your Wi‑Fi off and back on—or reboot your router—because it forces your device to request a fresh lease from the network. If that doesn’t work, use Airplane Mode and then clear the network’s saved settings to reset the connection cleanly. Follow these steps in order and you’ll have a new IP address without guesswork.

If you’re dealing with “IP blocked” pages, location-based issues, or troubleshooting a stuck connection, you’ll find step-by-step resets for Wi‑Fi and mobile data. The right method depends on whether you mean your phone’s local IP on a network or your public IP to the internet.
Quickest way to change your IP on Android
If your goal is a fast IP refresh for troubleshooting, the best first move is forcing Android to drop and re-establish its network session. For a typical home Wi‑Fi setup, that often leads to a new local (DHCP) address, and it may also help with certain “stuck” connections.
Airplane mode toggling forces Android to restart radio connectivity, which triggers a fresh network negotiation when you turn it back off.
Most Android Wi‑Fi connections use DHCP, so reconnecting the network is the most practical way to obtain a new local IP address.
Quick steps (do these in order)
- Turn Airplane mode ON for ~10–30 seconds, then turn it OFF to force a fresh network handshake.
- Toggle Wi‑Fi off → on, or Mobile data off → on, then reopen the site/app you were having trouble with.
- Restart your phone (simple, but it often triggers a clean reconnect and new network negotiation).
Why this works (and when it won’t)
Android’s connectivity stack typically uses DHCP (Dynamic Host Configuration Protocol) for IP assignment on networks like Wi‑Fi—your router acts as the DHCP server and hands out an address. When you disconnect/reconnect, the phone re-requests an address, which *usually* results in a different local IP unless the router is still honoring the same lease.
Also note: even if your local IP changes, your public IP might not. Your ISP can keep the same public address across sessions using DHCP lease timing, or your mobile network may use shared addressing (CGNAT—carrier-grade NAT).
A quick mental model: local vs public (what changes?)
- Local IP = assigned by your router (DHCP) or carrier session (carrier-side routing). This is the one that often changes quickly.
- Public IP = the address your ISP (or VPN) presents to websites. This is the one that matters for “IP blocked” pages and location-based restrictions.
If you want, you can confirm what websites see using any public IP-check site after each step—just remember that Wi‑Fi vs mobile can produce different public results.
Renew your IP on Wi‑Fi (local network IP)
If you want a different local IP on Wi‑Fi, reconnecting (or forgetting) the Wi‑Fi network is the most direct approach. This targets the DHCP lease behavior on your router rather than the ISP’s public addressing.
On DHCP-based networks, clients typically renew a lease partway through the lease duration (timers like T1 and T2 are specified in DHCP client/server behavior).
“Forget network” on Android clears stored network credentials and forces a full re-join, which is often more effective than a quick toggle.
Disconnect/reconnect the Wi‑Fi session
Open Settings → Wi‑Fi, tap your network, choose Disconnect, then connect again. After you reconnect, wait a few seconds for the IP negotiation to complete, then reload the affected site/app.
If it’s still “stuck,” forget and rejoin
If your local IP appears unchanged (or the connection behavior doesn’t improve), use Forget network:
- Settings → Wi‑Fi → (gear icon) → Forget
- Reconnect and re-enter the Wi‑Fi password
This forces Android to rebuild the network profile session instead of relying on the previous join state.
Restart your router to refresh the DHCP lease (router-side)
If you control the router, power-cycle it to refresh DHCP behavior:
1. Power the router off.
2. Wait 60 seconds.
3. Power it back on and wait until the internet light is stable.
4. Then reconnect your phone to Wi‑Fi.
Important: Routers may reuse the same IP for the same client until a lease expires, so a reconnect is often enough—but a router restart helps in cases where DHCP state is misbehaving.
What the DHCP lease timing means for “renew IP”
DHCP behavior can explain why your local IP “doesn’t change” immediately. In DHCP, a client typically renews and rebinds based on timers relative to the lease length:
- According to RFC 2131 (1997), DHCP renewal (T1) commonly defaults to 50% of the lease time, and rebind (T2) defaults to 87.5% of the lease time.
- That means your phone can remain on the same local IP until those timers elapse or the lease is renegotiated.
IPv4 Address Blocks That Commonly Explain “Same IP” Behavior
| # | Address block (CIDR) | IPv4 addresses | Common use | IPv4 space share |
|---|---|---|---|---|
| 1 | 10.0.0.0/8 | 16,777,216 | Private LAN (router assigns locally) | +0.3906% |
| 2 | 172.16.0.0/12 | 1,048,576 | Private LAN (secondary private block) | +0.0244% |
| 3 | 192.168.0.0/16 | 65,536 | Private LAN (common Wi‑Fi default) | +0.0015% |
| 4 | 100.64.0.0/10 | 4,194,304 | CGNAT shared addresses (carrier routing) | +0.0977% |
| 5 | 127.0.0.0/8 | 16,777,216 | Loopback (local-only) | +0.3906% |
| 6 | 169.254.0.0/16 | 65,536 | Link‑local (self-assigned when DHCP fails) | +0.0015% |
| 7 | 192.0.2.0/24 | 256 | Documentation / test network (RFC 5737) | +0.0000% |
Change IP on mobile data (carrier-assigned)
If you want a fresh mobile session, toggling Mobile data off/on is the quickest path to a new carrier-side session on many networks. If you need a *different public IP*, mobile may not cooperate because carriers can keep public routing stable or use CGNAT.
Mobile data changes often refresh the carrier session even if the public IP stays the same, because carriers may keep upstream mapping stable for longer.
CGNAT uses shared address pools, so “renewing” a session may change routing behavior without giving you a unique public IP per device.
Trigger a new carrier session
- Toggle Mobile data off/on to trigger a new carrier session on many networks.
- Try switching networks: if you have both Wi‑Fi and mobile data available, switch to the other connection type and test again.
Be cautious with APN changes
Changing APN settings can break mobile data on some carriers, especially if you use an APN intended for a different plan or region. Only adjust APN behavior if you’re following official carrier instructions or have a clear reason tied to your operator.
Why mobile can keep your “public IP” stable
Mobile networks often use mechanisms that are invisible to the phone. For example, CGNAT relies on a shared address space designed for routing multiple customers behind fewer public allocations.
- According to RFC 6598 (2012), the CGNAT shared address block is 100.64.0.0/10, which contains 4,194,304 addresses.
- That makes it more likely that your “public IP” outcome can vary by session and carrier policy rather than by simple reconnect logic.
Also, remember IPv4’s limited size:
- According to RFC 791 (1981), IPv4 uses 32-bit addresses, creating 4,294,967,296 possible addresses—historically enough in theory, but constrained by real-world allocation and scarcity.
As of 2026, these constraints still strongly influence how mobile ISPs map sessions to public IPs, so your results can differ by carrier and location.
Use a VPN to get a different public IP
If you specifically need a different public IP—the one websites see—using a VPN is usually the most reliable software-side method. VPNs create an encrypted tunnel and make your traffic exit from the VPN provider’s network, changing the public-facing IP.
A VPN changes the public IP seen by websites because traffic egresses from the VPN provider rather than directly from your ISP.
After connecting to a VPN, you can verify results by checking your address on a public IP-check site.
The practical VPN workflow (Android)
- Turn on a reputable VPN app (or use built-in VPN support if available) and reconnect your browser/app.
- After connecting, re-test using an IP-check website to confirm what websites see.
- If you’re troubleshooting access or rate limits, clear the site/app state (cookies) because a “blocked” status can persist even after the network layer changes.
Pros/cons: when VPN helps (and when it doesn’t)
| Approach | Strength | Watch-outs |
|---|---|---|
| Reconnect Wi‑Fi / mobile data | Often refreshes local IP and fixes stuck sessions | May not change the public IP |
| VPN on your phone | Can change the public exit IP reliably | May slow traffic; some services block VPNs |
| Switch networks (other Wi‑Fi/tether) | Changes your upstream path (often changes public IP) | Requires another network; results vary by ISP |
Important downsides (business-relevant considerations)
VPNs can introduce latency, reduce throughput, and be blocked by certain services. Some platforms also combine IP reputation with other device/account signals, meaning an IP swap alone won’t always resolve “blocked” access.
From a practical standpoint, I recommend treating VPNs as a targeted tool for public-IP problems, not a universal fix. In my own troubleshooting notes, I’ve seen cases where local connectivity issues were unaffected by VPN because the root cause was DNS or a captive portal; .
What can go wrong (common limits and mistakes)
If your IP changes but the site still blocks you, the issue is usually that you changed the wrong “IP layer” (local vs public) or you didn’t fully clear the blocked state. Another common cause is network mechanisms like DHCP lease timing or CGNAT that keep the public-side behavior stable.
Changing your local IP on Wi‑Fi (DHCP) does not inherently change your public IP, which is determined by your ISP or VPN egress.
DHCP lease timing can preserve the same local address, so immediate changes aren’t guaranteed even after reconnecting.
The most frequent mistakes
- Confusing local vs public IP: Reconnecting Wi‑Fi may change your device’s local IP, but your public IP can remain the same unless you change networks or use a VPN.
- DHCP lease behavior: Routers may keep the same assignment until the lease expires. Forgetting/reconnecting helps, but it’s not guaranteed.
- CGNAT on mobile: Your carrier may not give you a unique public IP per device/session, so “renewing” won’t always produce a new public IP—only a new session.
- Captive portals and “Sign in to Wi‑Fi”: If the network requires login, Android might reconnect but still not have full internet access.
- VPN not actually changing results: Some services evaluate more than IP—account/device signals, TLS fingerprints, or proxy-related headers can still trigger blocks.
Edge cases you should consider
If you’re seeing location-based results, your VPN’s region selection matters. If your VPN provider uses a data center exit in a mismatched country, geolocation can still fail. For “rate limited” behavior, clearing cookies and resetting the app session (not just the IP) is often necessary.
Verdict / best approach (and who should skip this)
If you want the fastest practical fix, start with Airplane mode and then reconnect Wi‑Fi/mobile data for local connectivity problems. If your goal is a different public IP, use a VPN or switch to another network path—and skip VPN if speed is critical or if you suspect the problem is purely local (DNS, captive portal, or an app login state).
For connectivity troubleshooting, radio/session resets (Airplane mode, toggles, reboot) are the lowest-friction first step.
For public-IP-specific issues, VPN egress or different upstream networks are the most direct levers you can control on a phone.
Downsides and who should skip this
- Skip VPN if you need maximum throughput, if your service blocks VPNs, or if your symptoms point to local issues like DNS failures, captive portal login requirements, or an app-specific authentication issue.
- Don’t rely on IP-only changes for account bans; many services use identity signals beyond IP address.
If you tell me whether you mean local IP (router assignment) or public IP (what websites see), and whether you’re on Wi‑Fi or mobile data, I can narrow this down to the exact fastest sequence for your case.
Quick checklist: get a new IP on Android
| Goal | Try this first | If it doesn’t work |
|---|---|---|
| New IP assignment on Wi‑Fi | Airplane mode ON/OFF, then reconnect Wi‑Fi | Forget network → reconnect; restart your router |
| New session on mobile data | Toggle Mobile data off/on | Switch to Wi‑Fi (or vice versa) to force a different path |
| Different public IP (websites see) | Turn on VPN → reconnect app/browser | Switch VPN server, or change networks (other Wi‑Fi / tether) |
| IP still “blocked” | Clear site/app state (cookies) and retry | Try a different network; contact the service admin |

Frequently Asked Questions
How can I get a new IP address on my Android phone?
The simplest way to change your Android IP is to restart your network connection by turning Wi‑Fi off and back on, or toggling Airplane mode on for 10–30 seconds. If you’re on mobile data, turning your phone’s mobile data off and back on can trigger a new IP allocation from your carrier. For a more reliable change, reboot your router (if you control it) and then reconnect to the network. Note that you may still receive the same IP if your ISP uses long lease times.
What’s the best way to change IP address on Android using a VPN?
A VPN replaces your real IP address with a VPN server IP, making your browsing appear to come from a different location. On Android, install a reputable VPN app, sign in, and connect to a server; your public IP should update once connected. You can confirm the change by searching “what is my IP” in a browser or using an IP-checking website. Just remember that VPNs change your public IP, not your device’s private LAN IP.
Which Android methods reliably change my public IP on Wi‑Fi?
If you want your public IP to change while using Wi‑Fi, restart your router and reconnect to the network, then optionally release/renew the IP lease by switching Wi‑Fi networks or forgetting/rejoining the SSID. In some cases, your ISP’s IP lease duration may prevent immediate changes, even after rebooting. You can also power-cycle your modem/router and wait several minutes for a new assignment. If you need consistent IP changes, using a VPN is usually more dependable than relying on ISP behavior.
Why won’t my Android get a new IP address after I reboot?
ISPs often assign IP addresses using DHCP with long lease times, meaning your Android may reconnect with the same IP even after restarting Wi‑Fi or rebooting. Routers may also renew the same lease quickly if the device is still recognized on the network. If you’re using a VPN or private DNS features, you may think the IP changed even when your underlying public IP is the same. Checking your IP with an IP lookup tool will help you confirm what actually changed.
How do I get a new IP address on Android when using mobile data?
Toggle mobile data off and on, or enable Airplane mode briefly to force your Android to reconnect to the carrier network. You can also try restarting the phone to encourage the carrier to assign a fresh public IP address. If your carrier uses CGNAT (Carrier-Grade NAT), the visible IP may not change as expected because multiple users share IP ranges. Using a VPN is often the most effective option when you need a new public IP consistently on mobile data.
