Learn everything you need to know about IP addresses and how they work
IPv4 uses 32-bit addresses (e.g., 192.168.1.1) providing about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:0db8::1) offering virtually unlimited addresses for the growing internet.
Every device connected to the internet needs a unique IP address to send and receive data. It's like a postal address for your device, allowing data packets to find their way to and from your device.
Dynamic IPs change each time you connect to the internet, assigned automatically by your ISP. Static IPs remain constant and are often used for servers, business networks, or specific services.
Public IPs are visible on the internet and assigned by your ISP. Private IPs (like 192.168.x.x) are used within local networks and not directly accessible from the internet.
Regional Internet Registries (RIPE, ARIN, APNIC, etc.) allocate IP address blocks to ISPs. Your ISP then assigns an IP from their pool to your connection when you go online.
Most home internet connections use dynamic IP allocation. Your IP may change when you restart your router, after your DHCP lease expires, or when your ISP performs network maintenance.
Your ISP provides your IP address and routes your internet traffic. DNS (Domain Name System) translates human-readable domain names (like google.com) into IP addresses that computers use to communicate. Your ISP typically provides DNS servers, though you can use alternatives like Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1).
Understanding what your IP reveals and how to protect your privacy
Your IP address reveals more information than you might think:
Websites and advertisers use your IP address for various purposes:
Understanding the key networking concepts
| Term | Meaning | Example |
|---|---|---|
| IP Address | Unique device identifier on the internet | 192.168.1.1 |
| DNS | Resolves website names to IPs | google.com → 142.250.72.238 |
| ISP | Provides internet connectivity | AT&T, Verizon, Starlink |
Common questions about IP addresses, privacy, and security
It identifies your device to websites and servers for communication. When you visit a website, your IP address tells the server where to send the requested data back to your device.
No — it shows an approximate city or region, not your street address. IP geolocation databases can typically pinpoint your location to within a city or metropolitan area, but they cannot reveal your exact home address.
Yes — ISPs often assign dynamic IPs that change periodically or after rebooting your router. Most residential internet connections use dynamic IP addressing, which means your IP can change when your DHCP lease expires or when you restart your network equipment.
Use a VPN, proxy server, or Tor browser to mask your public IP. A VPN (Virtual Private Network) is the most secure option, encrypting all your internet traffic and routing it through a server in a location of your choice.
Having your IP address alone is not enough for someone to hack you. However, combined with other vulnerabilities, it could be used in targeted attacks. Always keep your software updated, use strong passwords, and enable firewalls to protect your network.
IPv4 uses 32-bit addresses (like 192.168.1.1) and can support about 4.3 billion addresses. IPv6 uses 128-bit addresses (like 2001:0db8::1) and can support virtually unlimited addresses. IPv6 was developed to solve the IPv4 address shortage as more devices connect to the internet.
Your IP address is already visible to every website you visit and is not considered highly sensitive information. However, you should be cautious about publicly posting it, as it could be used for DDoS attacks or to gather information about your general location.
Check the IP address displayed on this page. IPv4 addresses have four groups of numbers separated by periods (e.g., 192.0.2.1), while IPv6 addresses have eight groups of hexadecimal digits separated by colons (e.g., 2001:0db8:85a3::8a2e:0370:7334). Most internet connections currently use IPv4.
