prips + hakrevdns: a handy combo for enumerating IPs and reverse-resolving them to hostnames
kingslyj · x · 2026-11-08
The author shares a TIL about prips (apt-installable on Debian), a small tool that prints every IP in a CIDR block or start-end range, with options for CIDR notation, custom delimiters, hex/dec/dot formats, increments, and excluded ranges.
The post quotes @hakluke's hakrevdns tool: feed it IP addresses and it reverse-resolves them to hostnames, useful for discovering domains and subdomains belonging to a company from its IP space. Used together — prips to enumerate the range, hakrevdns to reverse-resolve — this is a practical combo for asset discovery and subdomain enumeration, whether run manually or handed to an automated recon agent.
