Networking

Calculate address ranges, masks and subnet boundaries using explicit IP conventions.

Find an IPv4 network boundary, final address, block size and conventional usable-host count.

Convert an IPv4 CIDR prefix length to its dotted-decimal subnet mask.

Find the IPv4 network boundary from an address and CIDR prefix length.

Find the conventional broadcast address for an IPv4 subnet with a prefix from 0 to 30.

Find a canonical IPv6 network address and an exact address count for the chosen prefix.

Cover an inclusive IPv4 address range with the smallest aligned set of CIDR blocks.

Split an aligned IPv4 network into equal-prefix subnets and list their boundaries.
