Подсети и CIDR

IPv4 and IPv6 both work. You may append /24 here.

Accepts a bit count (24), a netmask (255.255.255.0) or a wildcard (0.0.0.255).

One per line as "name, hosts". To pin a length write "name, /64", the right way for IPv6.

One block per line. Adjacent blocks merge too, not just overlapping ones.

One block per line. Blocks outside the parent are ignored; blocks that overhang lose only the part inside.

64 addresses per page. Leave 0 to start at the first host.
