The DNS server does not require configuration. However, you may wish to view the list of
computers known by the DNS, edit the host name or IP address of a computer on the list,
or manually add a new computer to the list.

3.3.3.6.3 Configuring DHCP Server
Your device's Dynamic Host Configuration Protocol (DHCP) server makes it possible to
easily add computers that are configured as DHCP clients to the home network. It provides
a mechanism for allocating IP addresses and delivering network configuration parameters
to such hosts. The device's default DHCP server is the LAN bridge. A client (host) sends
out a broadcast message on the LAN 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 then it also
receives current information about network services, as it did with the original lease,
allowing it to update its network configurations to reflect any changes that may have
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 then makes
the IP address available for use by others.
