    Applications IP Addressing Devices on an IP network are located by their IP addresses, which is a 32 bit number divided into four 8 bit fields. The IP address identifies both the network and the host device (also known as a node) on that network. The address is usually written as the four decimal values for the fields (between 0 and 255) separated by decimal points;...

  • Page 26: Masks

    Applications Masks The portion of the IP address to use as the network address is specified by using a mask; a mask is the contiguous number of bits to be used for the network address all set to 1. When the mask is logically ANDed with an IP address, the result is the network address.
  • Page 27 Applications The router allows mask sizes from 8 to 32 bits. The subnet mask size determines how many bits of the host field of the original IP network address will be used for the creation of subnets. In this example, specifying a mask size of 26 will produce a subnet size of 2 bits. Two bits gives 4 possible sub-network addresses from the original IP network address.

  • Page 28: Ip Default Gateway

    Applications IP Default Gateway An IP default gateway is an IP router that is resident on the local IP network that this router is connected to and is used to route IP frames for destination networks that do not exist in the routing table.
