An IP address uniquely identifies a device on an IP network. Allocating, recycling, and documenting IP addresses and subnets in a network can get confusing very quickly if you have not laid out an IP addressing plan. A sound plan will help you prepare the network foundation to support additional services such as unified communications, wireless access, and enhanced network security. IPv4 Basics IP addressing is core to the design of a network and the functionality of the DGS-6600 Switch; it provides the base for all other network and user services on the DGS-6600 switch. IP version 4 (IPv4) addresses, are addresses which uniquely identify a device on an IP network. IPv4 addresses are 32 bits in length and are typically communicated across the network in a format referred to as dotted decimal. • The 32 binary bits are: • Divided into a network and host portions • Placed into four octets of 8 bits. • Each octet can be converted to binary. Consider this IP address, which is presented in dotted decimal: 10.83.33.1. The address breaks down into the following octets: 10, 83, 33, 1 The value in each octet ranges from 0 to 255 decimal, or 00000000- 11111111 binary. In binary, the address 10.83.33.1 is represented as: 00001010 01010011 00100001 00000001 DGS-6600 Configuration Guide 194
