IPv6 CIDR range for 2607:ff68:107::/70

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 2607:ff68:107::/70

The prefix identifies a network with 58 host bits. Every address from the first address through the last address belongs to this range.

CIDR prefix

2607:ff68:107::/70

Network mask

ffff:ffff:ffff:ffff:fc00::

Prefix length

/70

Host bits

58

First address

2607:ff68:107::

Last address

2607:ff68:107:0:3ff:ffff:ffff:ffff

Total addresses

288230376151711744

Total addresses (human readable)

2^58 addresses (288,230,376,151,711,744; about 288.23 quadrillion)

How this range is calculated

  1. 1The /70 prefix keeps the first 70 network bits fixed.
  2. 2Setting all 58 host bits to zero produces 2607:ff68:107::.
  3. 3Setting those host bits to one produces 2607:ff68:107:0:3ff: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.
