Designing the Address Standard for our Internetwork

Designing the Address Standard for our Internetwork
To assist troubleshooting and expedite adding new hosts to the network, use addresses that fit a common pattern across all subnets. Each of these different device types should be allocated to a logical block of addresses within the address range of the network.

Some of the different categories for hosts are:
General users
Special users
Network resources
Router LAN interfaces
Router WAN links
Management access


For example, when allocating an IP address to a router interface that is the gateway for a LAN, it is common practice to use the first (lowest) or last (highest) address within the subnet range. This consistent approach aids in configuration and troubleshooting.

Similarly, when assigning addresses to devices that manage other devices, using a consistent pattern within a subnet makes these addresses easily recognizable. For example, in the figure, addresses with 64 - 127 in the octets always represent the general users. A network administrator monitoring or adding security can do so for all addresses ending in these values.
