The prefix length can range from 0 to 128, due to the larger number of bits in the address. However, by convention, a subnet on broadcast MAC layer networks always has 64-bit host identifiers. [13] Larger prefixes (/127) are only used on some point-to-point links between routers, for security and policy reasons. [14]
The first and last address in any network or subnet is not allowed to be assigned to any individual host. In the past, the recommended allocation for an IPv6 customer site was an address space with a 48-bit (/ 48) prefix. [20] However, this recommendation was revised to encourage smaller blocks, for example using 56-bit prefixes. [21]
For this purpose, an IP address is recognized as consisting of two parts: the network prefix in the high-order bits and the remaining bits called the rest field, host identifier, or interface identifier (IPv6), used for host numbering within a network. [1] The subnet mask or CIDR notation determines how the IP address is divided into network ...
An IPv6 network does not perform fragmentation in network elements, but requires end hosts and higher-layer protocols to avoid exceeding the path MTU. [ 20 ] The Transmission Control Protocol (TCP) is an example of a protocol that adjusts its segment size to be smaller than the MTU.

A network and wildcard mask combination of 1.1.1.1 0.0.0.0 would match an interface configured exactly with 1.1.1.1 only, and nothing else. Wildcard masks are used in situations where subnet masks may not apply. For example, when two affected hosts fall in different subnets, the use of a wildcard mask will group them together.
