IPv6 Subnet Calculator
Calculate IPv6 address ranges, subnets, total address capacities, and binary notations.
The Importance of IPv6 Subnetting
IPv6 addresses consist of 128 bits, representing a virtually infinite pool of internet coordinates. Subnetting is used to divide networks into smaller chunks (prefixes) like /48 or /64 to route internet packets efficiently.
This calculator expands short IPv6 notations, determines the network range parameters, and shows total address capacity based on subnet masks.
Usein kysytyt kysymykset
A /64 prefix length is the standard subnet size for a single local network link, containing 2^64 (about 18.4 quintillion) addresses.
An IPv6 address has 128 bits, written in 8 groups of 4 hexadecimal characters separated by colons.
