To understand how IP routing works, we must first begin with the structure of IPv4 addresses. As described in the last section, these are 32 bits in length. They are written in a dotted decimal notation in groups of 4 bytes (for example, 192.168.122.5). A given number of bits in that network prefix is used to identify the network where the packet should be delivered, and the rest of the bits identify the particular host. Thus, all hosts in the same network must have the same prefix. Conventionally, the prefix is described in the CIDR notation with the starting address and the number of bits in the network portion of the address separated by a slash (192.168.122.0/30). The number can then be used to find out how many addresses ...
