IPv6 subnet calculator

IPv6 CIDR range for 2a00:1450:4000::/35

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.

Network details for 2a00:1450:4000::/35

The prefix identifies a network with 93 host bits. Every address from the first address through the last address belongs to this range.

CIDR prefix

2a00:1450:4000::/35

Network mask

ffff:ffff:e000::

Prefix length

/35

Host bits

93

First address

2a00:1450:4000::

Last address

2a00:1450:5fff:ffff:ffff:ffff:ffff:ffff

Total addresses

9903520314283042199192993792

Total addresses (human readable)

2^93 addresses (9,903,520,314,283,042,199,192,993,792; about 9.9 octillion)

How this range is calculated

  1. 1The /35 prefix keeps the first 35 network bits fixed.
  2. 2Setting all 93 host bits to zero produces 2a00:1450:4000::.
  3. 3Setting those host bits to one produces 2a00:1450:5fff:ffff:ffff:ffff:ffff: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.
