This page presents the BETA version of DDec, CAIDA's public DNS Decoding database, public interface.
Many organizations encode geographic location, router type, and other information into their hostnames, for example LosAngeles and edge in xe-9-3-0.edge5.LosAngeles1.Level3.net. By combing rules from multiple sources, DRoP and undns, DDec provides a single location for decoding DNS names.
Currently, DDec allows users to decode hostnames, find rules for individual domains, lookup encoding rules by name, or dump all the rule sets.
