This tool generates random public IP address which respects reserved IP addresses restrictions. RFC 1918 specfies that the following ranges are restricted for use in private internets only.
For the full range of reserved IP addresses see reserved IP addresses article at Wikipedia.
On initial load or click on generate button you can see that a random public IP address is shown in the output textarea. The output displayed valid public IP addresses in human-readable IPv4 format xxx.xxx.xxx.xxx (where xxx is a number from 0-255).
Optionally you can check or uncheck IP address lookup checkbox which reveals detailed information about given IP address (3rd party source).
