About this tool
Look up an IP address's version, whether it's public or private, and its reverse DNS hostname.
Frequently asked questions
What does "private" vs "global" mean?
Private IPs (like 192.168.x.x or 10.x.x.x) are only reachable within a local network; global/public IPs are routable on the internet — this is different from whether the address is actually assigned to anyone right now.
What is reverse DNS?
It's the hostname associated with an IP address (the reverse of a normal domain-to-IP lookup) — not every IP has one set up, so this may come back empty.
