FAQ
What is the difference between a public IP and a private IP?
A public IP is a globally unique egress address used for internet communication; a private IP is assigned for use inside a local network and cannot be reached directly from the public internet. A router’s NAT feature maps private IPs to the public IP to enable internet access.
What is the difference between IPv4 and IPv6?
IPv4 addresses are 32 bits, usually written in dotted-decimal form such as 192.168.1.1, with an address space of roughly 4.3 billion. IPv6 uses 128 bits, offering a vastly larger address space written as colon-separated hexadecimal, and solves IPv4 address exhaustion.
How can I look up the IP of another device or website?
To find the geolocation of another public IP, enter that address in an IP Location Lookup tool. To find the IP address behind a domain name, use a DNS lookup tool to resolve the domain.
What is a public egress IP? Can my IP change?
A public egress IP is the address your devices show to the internet when accessing it. Residential broadband typically uses dynamic IPs that may change after a router reboot, while business lines usually have a fixed IP. This tool shows your current egress IP.
Why should I check my own IP address?
Knowing your public IP helps with remote desktop connections, hosting a server, configuring firewall whitelists, troubleshooting network issues and confirming whether a VPN is active. It is one of the most basic checks in network operations.
