CIDR to IP list
Expand CIDR blocks, ranges or a list of them into every single IP address, one per line. Copy the list or download it as a text file.

How it works
A CIDR block like 192.0.2.0/28 holds 16 addresses, from 192.0.2.0 to 192.0.2.15. This tool writes every one of them out, which helps when a scanner, a monitoring tool or a spreadsheet needs single addresses rather than blocks.
On an IPv4 network the first address names the network and the last is the broadcast address, so devices can't use them. Tick "skip network and broadcast" to list only the usable host addresses. Blocks of /31 and /32 have nothing to skip: a /31 is a point-to-point link where both addresses work (RFC 3021). IPv6 has no broadcast address, so nothing is skipped there.
Lists stop at 65,536 addresses. Even a small IPv6 network (a /64) holds about 18 quintillion, far too many to write out.
To see just the first and last address of a block, use CIDR to IP range. To pick a few addresses at random, use the random IP generator.
