What Is My IP?
Check your public IP address
What Is My IP?
Displays your current public IP address and related information. This is the address that websites and online services see when you connect to them.
How to use the IP Checker
- •Open the tool and your public IP address is detected and displayed automatically. No input is required.
- •View IP details including the IP version (IPv4 or IPv6) and the address itself.
- •Check additional information such as your approximate geographic location, ISP (Internet Service Provider), and whether you are using a VPN or proxy, if available from the lookup.
- •Copy your IP address with one click for use in firewall configurations, server whitelisting, or troubleshooting.
What is an IP Address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. It serves two fundamental purposes: identifying the host (or network interface) and providing the location of the host in the network for routing.
IPv4 addresses are 32-bit numbers written as four octets separated by dots (e.g., 192.168.1.100). Each octet ranges from 0 to 255, giving a total of about 4.3 billion possible addresses. This seemed abundant in the 1980s but became insufficient as internet-connected devices proliferated. IPv4 address exhaustion was officially declared by IANA in 2011.
IPv6 addresses are 128-bit numbers written as eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). This provides approximately 3.4 x 10^38 addresses -- enough for every grain of sand on Earth to have trillions of addresses.
Your public IP address is assigned by your ISP and is the address that external servers see when you make requests. It is different from your private IP address (like 192.168.x.x or 10.x.x.x), which is used within your local network. Your router performs Network Address Translation (NAT) to map private addresses to your single public IP.
Knowing your public IP is essential for configuring remote access, setting up servers, whitelisting in firewalls, debugging network issues, and verifying that your VPN is working correctly.
Common use cases
- •VPN verification: Confirm that your VPN is active by checking that your displayed IP address belongs to the VPN provider's network rather than your actual ISP.
- •Server configuration: When setting up firewalls, security groups (AWS), or IP whitelists, you need to know your current public IP to grant yourself access.
- •Remote access setup: Configuring port forwarding, dynamic DNS, or SSH access to your home network requires knowing your public IP.
- •Network troubleshooting: Verify your internet connection and identify whether your traffic is routing through the expected ISP or proxy.
FAQ
Q: Why does the tool show a different IP than what I see in my router settings? A: Your router settings show your private/local IP (e.g., 192.168.1.x). This tool shows your public IP, which is the address assigned by your ISP to your router's external interface. NAT translates between the two.
Q: Does my IP address reveal my exact location? A: No. IP geolocation is approximate, typically accurate to the city or region level. It cannot pinpoint your street address. The location shown is based on ISP registration data.
Q: Why does my IP address change sometimes? A: Most residential ISPs assign dynamic IP addresses that can change periodically (when your router restarts or your DHCP lease expires). For a fixed address, you can request a static IP from your ISP or use a dynamic DNS service.
