They use an eight-bit network number and a 24-bit node number.

  • Page 84: Netmask

    Reference Manual for the WG602 v2 54 Mbps Wireless Access Point This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network. For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host.
  • Page 85 Reference Manual for the WG602 v2 54 Mbps Wireless Access Point Subnet addressing allows us to split one IP network address into smaller multiple physical networks known as subnetworks. Some of the node numbers are used as a subnet number instead. A Class B address gives us 16 bits of node numbers translating to 64,000 nodes.
  • Page 86 Reference Manual for the WG602 v2 54 Mbps Wireless Access Point The following table lists the additional subnet mask bits in dotted-decimal notation.
