Subnet addresses
The Subnet Address type is one that is only used in reference to IPv6 addresses.It represents an IPv6 address subnet. This means that the address will likely be a series of hexadecimal characters followed by a double colon, followed by a "/", and then a number less than 128 to indicate the size of the subnet. An example would be:
fd5e:3c59:35ce:f67e::/64
- The hexidecimal characters represent the IPv6 subnet address.
- The "::" indicates 0's from that point to the left. In an actual address for a computer, the hexadecimal characters that would take the place of these zeros would represent the device address on the subnet.
- /xx, in this case /64 represents the number of bits in the subnet.This will make a range that can potentially include 18,446,744,073,709,551,616 addresses. For those wanting to use English rather than math, that is 18 Quintillion.
