IP addresses that are used in Oracle Solaris 11 documentation conform to RFC 5737, IPv4 Address Blocks Reserved for Documentation (https://tools.ietf.org/html/rfc5737) and RFC 3849, IPv6 Address Prefix Reserved for Documentation (https://tools.ietf.org/html/rfc3849). IPv4 addresses used in this documentation are blocks 192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24. IPv6 addresses have prefix 2001:DB8::/32.
To show a subnet, the block is divided into multiple subnets by borrowing enough bits from the host to create the required subnet. For example, host address 192.0.2.0 might have subnets 192.0.2.32/27 and 192.0.2.64/27.
