        About reverse DNS and IP addresses

        How do you do a reverse IP lookup?

        Enter an IPv4 or IPv6 address above and select Lookup. Reverse DNS queries PTR records for a hostname associated with the address. A PTR record may be missing, and its hostname alone does not prove ownership or identify every site hosted at that address.

        What is the difference between private, loopback and public IP addresses?

        Private IPv4 addresses include 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16; IPv6 unique local addresses use fc00::/7. They are intended for local use, not public internet routing. Loopback addresses refer to the same device: 127.0.0.0/8 in IPv4 and ::1 in IPv6. Public addresses can be globally routed, subject to network configuration. Other special-purpose ranges exist, including IPv6 link-local addresses.
