IP Address Lookup
Look up public IPv4 and IPv6 addresses. See approximate location, ISP, ASN, and reverse DNS with clear privacy labels.
Examples
Look up a public IPv4 or IPv6 address
Enter an address above or use My Public IP. Results show only fields returned by the provider.
How to use
- Enter an IPv4 or IPv6 address, or choose My Public IP.
- Select Lookup. Results show only fields returned by the provider.
- Copy details or export JSON. Read the disclaimer about approximate location.
Examples
Check a resolver
Look up 8.8.8.8 to see Google Public DNS network attribution and any published reverse DNS.
IPv6 edge
Look up your ISP’s IPv6 prefix to confirm ASN and organization fields when available.
Public addresses only. Rate limits apply on the server. Set IPINFO_TOKEN for ipinfo.io; otherwise ip-api.com is used with its fair-use limits.
FAQ
- Does this show my exact address?
- No. Geolocation is approximate and often reflects the ISP or VPN egress, not a home address.
- Are private IPs looked up externally?
- No. RFC1918, loopback, link-local, and similar ranges stay on the server for classification only.
