What it is

An IP address identifies a host in a network. There are IPv4 and IPv6, plus private and public ranges.

How it works

Check address type, geo, AS affiliation and WHOIS. Private ranges have no public geo/WHOIS.

Examples

  • Private IPv4: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16.
  • Loopback: 127.0.0.0/8.

Limitations & notes

GEOIP is approximate and depends on databases. Proxies/VPN may distort detection.

FAQ

  • Why is my location off? GEOIP is an estimate, not GPS.
  • What is CIDR? Prefix notation like /24.
