Interface: IPv6Subnet

An IPv6 prefix (a CIDR block), given by IPv6.parseCIDR. The addresses are in compressed form ('2001:db8::').

Properties

firstHost: string

The first address of the block, its host bits zero ('2001:db8::' for 2001:db8::1/64). IPv6 has no broadcast address, so no address is reserved.

ipCount: bigint

The number of addresses in the block: 2 to the power of 128 - prefixLength, as a bigint (18446744073709551616n for a /64).

lastHost: string

The last address of the block, its host bits one ('2001:db8::ffff:ffff:ffff:ffff' for 2001:db8::/64).

prefixLength: number

The prefix length, from 0 to 128.
