Domain Routing

Domain routing is used in multi-router local network configurations. Normally,

to access a device connected to one router from another router on the network,

its IP address must be used. Activating domain routing (by clicking in the

appropriate check box) allows the user access to the computer by name (as well

as IP address).

8.8b IP Address Distribution

The FiOS Router’s DHCP server makes it possible to easily add computers

configured as DHCP clients to the network. It provides a mechanism for

allocating IP addresses to these hosts and for delivering network configuration

parameters to them.

For example, a client (host) sends out a broadcast message on the network

requesting an IP address for itself. The DHCP server then checks its list of

available addresses and leases a local IP address to the host for a specific period

of time and simultaneously designates this IP address as “taken.” At this point,

the host is configured with an IP address for the duration of the lease.

The host can choose to renew an expiring lease or let it expire. If it chooses to

renew a lease, it will also receive current information about network services,

as it did with the original lease, allowing it to update its network configurations

to reflect any changes that occurred since it first connected to the network. If

the host wishes to terminate a lease before its expiration, it can send a release

message to the DHCP server, which will then make the IP address available for

use by others.
