Detailed explanation-1: -10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128.

Detailed explanation-2: -The subnet prefix always contains 64 bits. These bits include 48 bits for the site prefix, in addition to 16 bits for the subnet ID.

Detailed explanation-3: -IPv6 doesn’t have a subnet mask but instead calls it a Prefix Length, often shortened to “Prefix”. Prefix length and CIDR masking work similarly; The prefix length denotes how many bits of the address define the network in which it exists.

Detailed explanation-4: -The prefix length determines the size of the subnet and is the number of 1 bits in the netmask. With variable-length subnetting, the prefix length does not have to be a multiple of 8. For example, you can have the IP address 192.168. 123.224, with a netmask = 255.255.
