Check an IP address's reputation

Enter an IP address to see who owns it, its reverse DNS name, and whether it appears on public blocklists used to flag spam and abuse.

How this works
  • We only run public DNS lookups (reverse DNS, Team Cymru for the network owner, and a sample of DNS blocklists). We never connect to the IP itself.
  • The IP you enter is used to produce this result and isn't stored.

You're viewing a shared result.

VirusTotal

Important limitation

Blocklists can lag, can list an entire shared range, and don't cover everything. A listing is a strong reason for caution, not proof of malice; a clean result isn't a guarantee of safety.
