IP Tools Suite

Use this tool to calculate detailed network information for an IP range.

Enter an IP address with CIDR notation (e.g., 192.168.1.0/24)

Use this tool to find out what are the complement IP ranges of given IP ranges.

For example: complement ranges of 0.0.0.0/2 are 64.0.0.0/2 and 128.0.0.0/1

Use this tool to find out summarized IP ranges from a given list of IP addresses.

If IPs are next to each other, they will be combined into bigger IP ranges.
For example: a list of IPs from 10.0.0.0 through 10.0.0.31 will be combined into 10.0.0.0/27
