Reverse IP Lookup
This site does a reverse DNS lookup of an IP address by searching domain name registry and registrar tables.
IP addresses are four numbers in the range of 0 to 255 separated by periods.
You may be able to identify the domain name of a spammer sending you spam email or the domain name of a computer
trying to break into your firewall or someone trying to hack your system.
You may also be able to use this information to determine the name of the internet service provider
that is assigned to a particular IP address.
