SophosLabs IP Address Classification Lookup

SophosLabs performs significant analysis to determine an IP address's classification in order to avoid any mis-classifications. If you believe an IP address to be mis-classified, you can check its current classification using this lookup tool, and if appropriate, send a request to SophosLabs to exempt the IP address from its current classification.

For information on how we classify IP addresses, read the SophosLabs IP address classification policy.
