Show HN: ActiveDNS, a free DNS search service
activedns.netHi, ActiveDNS is a project I’ve published online and has running for a couple of months now. It is a search engine for a DNS dataset I am constantly building. The purpose of it is to provide an accurate searchable database of domains, delegations and ip addresses and my initial motivation to make it was the need to look up CIDR ranges and find all associated IP adresses.
From the dataset, I am publishing monthly extracts of all observed registrable domain and top N hostnames. I’m sure I will find more interesting use cases for it later.
