How to Find Your IP Address: A Complete Guide

What Is an IP Address?

An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network. Think of it as your device's postal address on the internet — it tells other servers where to send data when you request a webpage, send an email, or stream a video. Without an IP address, data wouldn't know where to go.

Public IP vs. Private IP Address

You have two types of IP addresses:

• Public IP address: The address your internet service provider (ISP) assigns to your home or office network. This is what websites see when you visit them. All devices on your home network share this one public IP.
• Private IP address: The address your router assigns to each device on your local network (e.g., 192.168.1.100). These are only visible within your home network — not on the internet.

How to Find Your Public IP Address

The fastest way: use an "IP checker" tool — it immediately shows the IP address that the internet sees you coming from.

Alternatively, type into your browser: what is my ip — Google shows it at the top of results.

How to Find Your Private IP Address

Windows

Open Command Prompt (search "cmd") → type ipconfig → look for "IPv4 Address" under your network adapter.

Mac

Go to System Preferences → Network → select your connection → the IP is shown on the right, or click Advanced → TCP/IP tab.

iPhone

Settings → WiFi → tap the (i) next to your network → see IP Address.

Android

Settings → Network & Internet → WiFi → tap the network name → Advanced → IP address.

IPv4 vs. IPv6

	IPv4	IPv6
Format	192.168.1.1 (decimal, 32-bit)	2001:0db8:85a3::8a2e:0370:7334 (hex, 128-bit)
Total addresses	~4.3 billion	340 undecillion (virtually unlimited)
Status	Still dominant	Increasingly common

IPv4 addresses ran out in 2011. The world is gradually transitioning to IPv6, which provides enough addresses for every grain of sand on Earth — many times over.

What Your IP Address Reveals

Your public IP can reveal:

• Your approximate geographic location (city/region level, not exact address)
• Your internet service provider (ISP)
• Whether you're using a VPN or proxy
• Your organization (for business IPs)

Your IP does NOT reveal your exact home address, your name, or your browsing history (unless subpoenaed from your ISP).

Dynamic vs. Static IP Addresses

Most home internet connections have dynamic IPs — they change periodically (when you restart your router or your ISP reassigns them). Static IPs never change and are typically used by businesses hosting servers, remote workers needing VPN whitelisting, and gamers who host servers.
