What Is My IP Address? How to Check It on Any Device

Your IP address is a unique string of numbers assigned to your device that identifies it on the internet and routes data to and from it.

An IP address is a number like 203.0.113.45 that your internet provider or router assigns to identify your device online. This guide answers the questions people search most: what an IP address is, the different types, how to find your IP on any device, what it reveals about you, why it matters for multi-account management, and how to change or hide it safely.

What Is an IP Address?

An IP address (Internet Protocol address) is a unique string of numbers assigned to every device on a network, used to send and receive data across the internet — much like a street address lets the postal service deliver mail to the right house.

Every time a device — a phone, laptop, or router — connects to the internet, your internet service provider (ISP) assigns it an IP address. That address tells servers, websites, and apps exactly where to send data back; when you load a webpage, the server uses your IP address to route the response to you.

Two IP versions run side by side today: IPv4 (four number groups separated by dots, like 203.0.113.45, offering roughly 4.3 billion unique addresses) and IPv6 (a longer alphanumeric format like 2001:0db8:85a3::8a2e:0370:7334, created because the pool of available IPv4 addresses has been running out as billions more devices come online).

What Are the Different Types of IP Addresses?

IP addresses are grouped by three criteria: scope (Public vs. Private), stability (Static vs. Dynamic), and version (IPv4 vs. IPv6) — each serves a different purpose.

Here's a quick summary of each type (per Cloudflare's Learning Center):

Your Private IP stays inside your network; the Public IP is what the internet actually sees

When you search "what is my IP," the result is always your Public IP — the single address representing your entire network (home, office, or mobile data) to the outside world. Your Private IP (usually 192.168.x.x or 10.x.x.x) is only visible to your own router.

What Is My IP Address? How to Check It Instantly

The fastest way to check your IP address (your Public IP) is to search "what is my ip" on Google or visit a dedicated IP-checking website — no software required, results show instantly.

• Option 1 — Google: search "what is my ip address"; Google displays your Public IP at the top of the results.

• Option 2 — Dedicated IP checker: sites like whatismyipaddress.com or ipinfo.io also show your approximate location, ISP, and connection type.

• Option 3 — GPM Login's fingerprint checker: view your IP address, timezone, and other browser-exposed parameters together — useful to confirm a proxy is working correctly.

• Note: these methods only show your Public IP. To see your device's Private IP, follow the per-device steps below.

How Do I Check My IP Address on Windows, Mac, or Mobile?

Each operating system has a quick built-in way to check your device's Private IP, usually found in network settings or a command-line tool.

• Windows: open Command Prompt, type ipconfig, and read the "IPv4 Address" line.

• macOS: go to System Settings → Network → select your connection; the IP address appears on the right, or run ifconfig in Terminal.

• Android: go to Settings → Wi-Fi → tap the gear icon next to your connected network → check "IP address."

• iPhone/iPad: go to Settings → Wi-Fi → tap the (i) icon next to your network → check "IP Address."

• Router: log into your router's admin page (often 192.168.1.1 or 192.168.0.1) to see both your Public IP (WAN) and every connected device's Private IP (LAN).

What Does My IP Address Reveal About Me?

Your IP address reveals your approximate location (usually city-level) and your internet provider, but it does NOT reveal your exact name or home address.

Still, it's a meaningful signal that websites, social platforms, and ad systems use to: localize content and pricing by country, flag unusual activity (many logins from the same IP in a short time), or — for MMO and e-commerce sellers — treat accounts as potentially linked if they share the same real IP address.

One risk that's often overlooked: even with a VPN or proxy running, a WebRTC leak (the browser protocol used for real-time video and audio) can still expose your real IP behind the scenes. That's why antidetect browsers let you disable or spoof WebRTC handling — see how this mechanism works on GPM Login's WebRTC IP leak knowledge page.

Why Does IP Address Matter for Managing Multiple Accounts?

Because platforms like Facebook, TikTok, and Shopee combine your IP address with your browser fingerprint to detect linked accounts — running many accounts on the same real IP is one of the fastest ways to get them all flagged and banned together.

Having supported hundreds of profiles for agencies and multi-store sellers, the most common mistake we see isn't skipping a proxy altogether — it's using one that doesn't match: the IP shows one country while the browser's timezone or language still points to another. That mismatch is exactly the kind of signal anti-fraud systems are built to catch.

A trustworthy IP setup for multi-account work needs three things working together: (1) a stable IP in the right region, (2) timezone and geolocation auto-matched to that IP, and (3) a browser fingerprint (Canvas, WebGL, User-Agent…) that's unique per account.

GPM Login handles all three in one place: its Proxies library supports HTTP, HTTPS, SOCKS4, and SOCKS5, lets you assign a dedicated proxy per profile or per group, checks whether a proxy is live before you use it, and automatically syncs each profile's timezone to its assigned proxy IP — cutting manual work and mismatch risk. See the full walkthrough in GPM Login's Proxies user guide.

Each profile pairs its own proxy IP, timezone, and fingerprint so platforms can't link the accounts together

How Do I Hide or Change My IP Address Safely?

There are three common ways to hide or change your IP: a VPN, a proxy, or an antidetect browser that pairs a proxy with a unique fingerprint per profile — the right choice depends on whether you need personal anonymity or need to run multiple accounts side by side.

For personal needs — unblocking region-locked content or protecting your privacy on public Wi-Fi — a VPN alone is simple and sufficient. But if your work involves running multiple Facebook, TikTok, or Shopee accounts side by side without getting them linked, an antidetect browser with a built-in proxy library is far safer and faster than manually pairing a VPN or proxy with a regular browser.

Frequently Asked Questions

Is my IP address the same as my identity?

No. Your IP address only shows your approximate location (usually city-level) and your internet provider — not your name, phone number, or exact home address. Combined with other data (cookies, logged-in accounts), though, it can help identify you.

Is it legal to change my IP address with a proxy or VPN?

Using a proxy or VPN to change your IP address is legal in most countries and widely used by businesses for security, testing, and legitimate account management. Legal issues only arise if you use it to break a platform's terms of service or the law — fraud, spam, or unauthorized access.

What's the real difference between IPv4 and IPv6, and does it matter to me?

IPv4 uses the familiar four-number format (like 203.0.113.45) and is running out because it only supports about 4.3 billion addresses; IPv6 uses a longer format built to support the growing number of connected devices. For most everyday use, both work fine — it only matters if you're renting a proxy or VPS and the platform you're targeting requires a specific IP type.

Why does my IP address keep changing even when I haven't done anything?

Most home internet connections use a Dynamic IP — your ISP reassigns a new address periodically or whenever you restart your router or modem. That's completely normal, not a sign of a problem or an attack.

Does using a proxy to change my IP slow down my connection?

There's some impact since traffic routes through an extra server before reaching its destination, but the slowdown depends on the proxy's quality and location. High-quality residential or ISP proxies typically stay fast enough for everyday browsing and account management.

Conclusion

Your IP address is the foundation that lets every device communicate on the internet — understanding it does more than answer "what is my IP address"; it helps you protect your privacy and run multiple accounts more safely. If your work requires changing IPs often alongside a distinct browser fingerprint per account, an integrated tool like GPM Login saves far more time than stitching together separate VPN, proxy, and browser tools.
