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.
The FiOS Router's DHCP server:
• displays a list of all DHCP hosts devices connected to the FiOS Router;
• defines the range of IP addresses that can be allocated in the network;
• defines the length of time for which dynamic IP addresses are allocated;
• provides the above configurations for each network device and can be
configured and enabled/disabled separately for each network device;
• can assign a static lease to a network computer to receive the same IP
address each time it connects to the network, even if this IP address is within
the range of addresses that the DHCP server may assign to other computers;
• provides the DNS server with the host name and IP address of each
computer connected to the network.
