IPduh is an Internet forensics and debugging engine. IPduh can be used as a general purpose web search engine, but answers best questions about the building blocks of the Internet.

IPduh is biased towards interpreting queries as being related to the Internet Infrastructure and it will answer queries in a way that facilitates the debugging of network issues, the debugging of Internet services, the research of Internet names, the research of Internet numbers, and the research of Internet security incidents.
