Playing mobile games and suddenly get an IP ban, your social accounts get shadowbanned, or some websites keep saying “access denied”? Many people assume “my account got banned,” but in many cases the real issue is that your public IP address has been blacklisted.
This article starts from a simple iPhone tutorial and extends to more practical scenarios, helping you understand:
- What a public IP is and why it gets “blocked”
- How to quickly check and change your public IP on iOS
- Pros and cons of using VPNs and anti-detect browsers
- How to manage multiple accounts more safely for cross-border marketing, e‑commerce, and social media networks
Why can’t you suddenly “get online”? First understand public IP
First, clear up a common misunderstanding:
The address you see in “Settings → Wi‑Fi” on your phone is just your local (private) IP. What websites and servers actually see is your public IP address.
- When you visit a website, open a game, log into Instagram, Facebook, Twitter, etc., the server records your public IP.
- If the system detects account farming, malicious attacks, frequent mass registrations, or violations of platform rules, it may block the entire IP range.
- As a result, even if you switch to a new account but keep using the same public IP, the platform will still “recognize you at a glance” and continue to limit or ban you.
This is the underlying reason why many people complain: “It was a brand‑new account, how did it get banned again so fast?”
How to check your public IP on iPhone
Scenario:
You suspect your IP has been banned, or you simply want to confirm how your current network “looks from the outside.”
On iOS, you don’t need any extra app to see your public IP:
- Open Safari.
- In the address bar, type
what is my public IP or just search “what is my IP”.
- Tap the first search result (any IP lookup site works).
- The page will usually show you:
- IPv4 address (typical format: 123.45.67.89)
- IPv6 address (a long string with colons)
Suggestions:
- Take a screenshot of your current IP so you can compare later after switching a VPN, to confirm it really changed.
- If you’re dealing with bans on games or websites, remember whether the IP segments before and after the ban are similar, so you can judge whether the whole IP range is risky.
Changing your public IP with a VPN: simple and effective, but limited
Most regular users first think of the method you see in many tutorials: download a VPN app from the App Store, connect to an overseas server, and let websites see a new IP.
Basic idea
Take the kind of app shown in the video as an example (e.g., tools like VPN Hub; this article does not endorse specific brands):
- Open the App Store and search for “VPN”.
- Pick a VPN app with decent ratings and download it.
- Open the app. It will typically:
- Prompt you to start a trial / buy premium — you can skip and use the free mode
- Ask to add VPN configurations — tap “Allow” and enter your device passcode
- Choose a server location:
- For example the US, Japan, Europe, etc., depending on where the target content is located
- Tap “Connect” and wait until the status changes to “Connected” / “Secure connection established”.
Once connected, go back to Safari and refresh the “what is my IP” page; you’ll clearly see:
- The IPv4/IPv6 addresses are now different.
- In the eyes of websites, game servers, and social platforms, you’re now “a user on a different network.”
This usually solves:
- IP‑based bans in games that cause login failures or matchmaking issues
- Social media services flagging your IP as risky, leading to endless captchas, login challenges, or feature limits
- Access to geo‑restricted websites and media content (streaming services limited to certain countries/regions)
Pros and limitations of VPNs
Pros:
- Extremely easy for regular users: install → connect → done
- One tap to change exit IP—very practical for unblocking or cross‑region access
- Adds a layer of encryption on public Wi‑Fi, slightly improving privacy
But if you’re doing cross‑border business or running accounts at scale, you’ll hit these issues:
- Many users share the same VPN endpoint IP, which makes it easy for platforms to classify it as “proxy traffic” and increase risk scoring.
- You can only change the IP, not your browser fingerprint: User‑Agent, screen resolution, fonts, Canvas, WebGL and more still expose your real environment.
- When operating many accounts, it’s hard to give each account an isolated environment. Accounts get “cross‑contaminated” and platforms can link them together.
At that point, a VPN alone is not enough; you need more professional anti‑detect browsers and multi‑account isolation tools.
If you need more than a “one‑time unblock”: why use an anti‑detect browser?
For the following types of users, simply changing your IP is often a drop in the bucket:
- Cross‑border e‑commerce sellers: multiple stores on Amazon, Shopee, Temu, and independent sites
- Overseas social media marketers: multi‑account matrices on TikTok, Twitter, Instagram, Facebook
- Ad buyers: multiple Google Ads / Meta Ads accounts, gray‑box testing
- Data collection & web scraping: high‑frequency access without getting blocked
For these platforms, risk control logic goes far beyond IP:
- Browser fingerprint (UA, resolution, language, time zone, Canvas, WebGL, etc.)
- System environment (OS version, fonts, plugins, WebRTC leaks)
- Behavioral patterns (login cadence, mouse/scroll patterns, navigation paths)
- Whether multiple accounts appear on the same device / same browser environment
If you just connect a VPN and log 5 ad accounts into the same browser, the platform still sees “one device + unstable IP” — highly suspicious.
This is exactly the use case for tools like MasLogin Multi‑Login Browser:
they don’t just change IP, they create an independent “virtual browser identity” for each account.
Practical scenarios: from “one‑time unblock” to long‑term stable operations
To help you decide which solution to use, let’s look at a few typical scenarios.
Scenario 1: Just temporarily accessing a blocked game or website
Characteristics:
- Only one account, used occasionally
- The site/game only blocked your current IP; changing IP restores access
- No plan to operate accounts at scale
Recommended approach:
- Simply use a VPN app on your iPhone and try again with a new IP.
- Verification: visit “what is my IP” to confirm the IP has changed.
- If you still can’t access it, that means:
- Either the entire IP range is blocked, or
- Your account itself has been permanently banned.
At this level, you don’t need an anti‑detect browser. A VPN is enough.
Scenario 2: Social media operations with multiple accounts frequently getting logged out or banned
Typical pain points:
- Multiple accounts across different platforms, constantly triggering “unusual login location” and “verify your identity.”
- New accounts get restricted or banned before they’re properly “warmed up.”
- Many accounts are operated in the same browser + on the same VPN.
At this point, the issue is no longer just your public IP; it’s that your device fingerprint is too odd or too similar across accounts.
A more robust strategy:
- Use a tool like MasLogin to give each account:
- A unique fingerprint profile
- A dedicated proxy IP
- Only log each account into its own browser profile; don’t mix environments.
- Manage accounts with realistic human behavior: no high‑frequency operations or mass spam campaigns right from the start.
If your Twitter accounts keep getting banned and you need unbanning and prevention strategies, you can search related guides on the MasLogin blog. They explain how to improve account survival rates from multiple angles: risk control, fingerprints, IP, and behavioral patterns.
For more stability: easily overlooked details that matter
Whether you’re just using a simple VPN or have upgraded to a multi‑login browser, several details are critical:
Avoid frequent country switching
- If the same account logs in from the US today, Europe tomorrow, and Asia the day after, it’s easily flagged as a hacked or stolen account.
- Ideally, fix each account to a stable country/city IP and time zone.
Match browser language with IP location
- Using a US IP together with a fully Chinese browser + China time zone raises your risk score.
- In tools like MasLogin, you can configure proper time zones and languages per environment.
Public Wi‑Fi + VPN is not as safe as you think
- Traffic on public networks can still be monitored, and your account behavior remains abnormal.
- Use your own stable, dedicated network whenever possible instead of piggybacking on public Wi‑Fi.
Behavior matters more than technical tricks
- Even with excellent IPs and near‑perfect fingerprints, if you mass‑register accounts or blast spam in a short time, you’ll still be banned.
- Act like a “normal user”: warm up accounts slowly and operate at a moderate pace for long‑term survival.

FAQ
Can I change my public IP on iPhone just by rebooting the router?
Sometimes, but it’s unreliable. Many ISPs assign “long‑lease” IPs, so your public IP may stay the same even after a router reboot. In comparison, using a VPN or proxy service is more controllable and repeatable.
Will using only a VPN completely prevent my accounts from being banned?
No. A VPN only addresses the “IP address” dimension. Platforms also assess browser fingerprints, behavior patterns, device information, and more. When running multiple accounts, it’s best to combine VPN/proxies with an anti‑detect browser.
Will changing my public IP affect my other legitimate accounts?
If you only occasionally change IP to access a blocked site, it’s usually fine. But if you routinely log many important accounts on the same device while frequently changing IPs, there is still correlation risk. For core business accounts, plan a stable, long‑term, and consistent environment.
