What Is My IP Address? Everything You Need to Know
Your IP address is your device's identity on the internet. Learn what it is, what it reveals, and how to find yours in seconds.
Every device connected to the internet has an IP address. It's how the internet knows where to send data — whether that's a webpage, a video, or a message. But most people have never looked at theirs, let alone understood what it means.
What is an IP Address?
IP stands for Internet Protocol. An IP address is a numerical label assigned to every device that connects to a network. Think of it like a postal address — without one, the internet has no way to deliver data to your device.
When you type a website URL into your browser, your computer silently translates it to an IP address using DNS (Domain Name System) before making the connection. That server then reads your IP address and sends the response back to you. Without an IP address, none of that works.
Two Types of IP Address
Public IP Address
Your public IP is assigned by your Internet Service Provider (ISP) and is visible to every website you visit. It identifies your entire network (your router) to the outside internet. Everyone in your home on the same Wi-Fi shares the same public IP.
You can see your current public IP right now at IPLocator.
Private IP Address
Your private IP is assigned by your router to each individual device on your local network. Your laptop, phone, smart TV — each gets its own private IP like 192.168.1.5. These addresses are only visible within your home network, never on the public internet.
IPv4 vs IPv6
Most IP addresses you'll encounter are IPv4 — four numbers separated by dots, like 203.0.113.42. IPv4 supports about 4.3 billion unique addresses, which the world has essentially run out of.
IPv6 was introduced to solve this. It looks like 2001:db8:85a3::8a2e:370:7334 — much longer, supporting a virtually unlimited number of addresses. Many modern connections use both simultaneously (called dual-stack). Read the full IPv4 vs IPv6 breakdown →
What Does Your IP Address Reveal?
When a website sees your IP address, it can determine:
- Your country and city — typically accurate within 25–50 miles
- Your ISP — Comcast, BT, Vodafone, etc.
- Your timezone — inferred from location
- Whether you're using a VPN — VPN IPs are often in known data centre ranges
- Your AS number — the network block your IP belongs to
What it cannot reveal: your exact street address, your name, or your browsing history. See the full breakdown of what your IP reveals →
How to Find Your IP Address

ipconfigand press Enter - Look for "IPv4 Address" under your active adapter
Your private IP on Mac:
- Open Terminal
- Type
ipconfig getifaddr en0(Wi-Fi) oren1(Ethernet)
Your private IP on iPhone/Android: Go to Settings → Wi-Fi → tap your network → look for IP Address.
Static vs Dynamic IP
Most home users have a dynamic IP — it changes periodically when your router reconnects. ISPs do this to manage their address pools efficiently.
Businesses often pay for a static IP — one that never changes. This is useful for hosting servers, remote access, and IP-based access controls. Learn the difference between static and dynamic IPs →
Why Does Your IP Address Matter?
Understanding your IP address matters for several practical reasons:
- Troubleshooting network issues — your IP is the first thing IT support will ask for
- Security — knowing your public IP helps you understand what you're exposing online. Can someone hack you with your IP?
- Access control — many services whitelist specific IPs for secure access
- Privacy — your IP is one of the main ways websites track and identify you
If you're concerned about privacy, a VPN replaces your real IP with one from a server in a location of your choice. Read our guide on hiding your IP address →
