Look up a public IPv4 or IPv6 address to see approximate network-registration details such as its provider, autonomous system, reverse hostname, and estimated location when available.
Run a lookup
Enter a public address in the IP lookup form. Private and reserved addresses are rejected. The result is informational: provider data can be incomplete, and a mapped location is not a precise device location.
Privacy and limitations
The public address you submit is sent to the lookup data provider for processing, and successful lookups are recorded in the local site activity log described on the home page. Do not enter an address unless you are comfortable with that disclosure.
