IPv6 CIDR range for ff02::/110

Calculate the network address, final address, mask, and exact address capacity of any IPv6 CIDR prefix.

Example: 2606:4700::/32

Host bits are normalized to the network address before the range is calculated.

CIDR calculation

Network details for ff02::/110

The prefix identifies a network with 18 host bits. Every address from the first address through the last address belongs to this range.

CIDR prefix

ff02::/110

Network mask

ffff:ffff:ffff:ffff:ffff:ffff:fffc:0

Prefix length

/110

Host bits

18

First address

ff02::

Last address

ff02::3:ffff

Total addresses

262144

Total addresses (human readable)

2^18 addresses (262,144; about 262.14 thousand)

How this range is calculated

  1. 1The /110 prefix keeps the first 110 network bits fixed.
  2. 2Setting all 18 host bits to zero produces ff02::.
  3. 3Setting those host bits to one produces ff02::3:ffff.

Network address

The normalized prefix base

CIDR notation describes a network, not a single host. If an address with host bits set is entered, this calculator normalizes it to the network base before calculating the range.
