IPduh is a general purpose Search Engine, but it is especially effective for conducting Internet research and addressing questions about the building blocks of the Internet.

IPduh is designed to interpret queries as being related to the Internet Infrastructure. It responds in ways that help debugging network issues, diagnosing problems on Internet services, researching Internet names, researching Internet Protocol numbers, investigating security incidents, and satisfying the couriosity of smart humans.

Experienced system administrators, network administrators, software engineers, abuse managers, threat hunters, and hackers will feel right at home. They will quickly understand the commands by trying some of the examples, and discover how IPduh's unique features speed up the information gathering process.

Other knowledge workers and less technical Internet users can benefit from using IPduh as well.

With practice, they will recognize the intelligence potential of each IPduh signal and learn how to use IPduh to generate deep insights.
