The Bogon Reference

A bogon prefix should never appear in the Internet routing table. Team Cymru’s Bogon Reference provides several resources for the filtering of bogon prefixes from your routers and hosts.

IP To ASN Mapping Project

Team Cymru provides query interfaces that allow for the mapping of IP addresses to BGP prefixes and Autonomous System Numbers (ASNs), based on BGP feeds from our 50+ BGP peers. Updated every 4 hours, this data is available through traditional WHOIS (TCP 43), DNS (UDP 53), HTTP (TCP 80), and HTTPS (TCP 443).

Malware Hash Registry

Similar to the Team Cymru IP address to ASN mapping project, the Malware Hash Registry (MHR) project is a look-up service with an added benefit: you can query our service for a computed MD5 or SHA-1 hash of a file and, if it is tracked malware, we return the last time we have seen it along with an approximate anti-virus detection percentage.

Unwanted Traffic Removal Service

UTRS is a system that helps mitigate large infrastructure attacks by leveraging an existing network of cooperating BGP speakers such as ISPs, hosting providers and educational institutions that automatically distributes verified BGP-based filter rules from victim to cooperating networks.

CSIRT Assistance Program

Team Cymru provides daily lists of compromised or abused devices for the ASNs and/or netblocks within a Regional and/or National CSIRT’s jurisdiction. The intent is to provide information directly into the hands of people who can use that insight.
