Identifying IPv6 Address Types

As Table 1 shows, you can quickly determine which type of IPv6 address you are dealing with by looking at the beginning part of the address-that is, the high-order bits of the address. Tables 2 and 3 also show examples of common IPv6 addresses that you can recognize directly from their colon-hexadecimal representation.

Table-1 Identifying IPv6 Address Types Using High-Order Bits and Address Prefix
