Carla Schroder looks at two handy IPv6 calculators along with some tricks for subnetting.

Calculating IPv6 Subnets in Linux

We're going to look at some IPv6 calculators, sipcalc and subnetcalc, and some tricks for subnetting without breaking our brains. Let's start with reviewing IPv6 address types. There are three types: unicast, multicast, and anycast. IPv6 Unicast The unicast address is a single address identifying a...

How to Calculate Network Addresses with ipcalc

The math behind IP addresses is convoluted. Our nice IPv4 addresses start out as 32-bit binary numbers, which are then converted to base 10 numbers in four 8-bit fields. Decimal numbers are easier to manage than long binary strings; still, calculating address ranges, netmasks, and subnets is a bit...
