The DNS Server allows use of hostnames on the local network (LAN). Computers can be reached using their names instead of IP numbers - the DNS server takes care of resolving names into numbers.

The DNS server resolves requests it knows the answer to. Otherwise it asks the Operator's DNS server before answering back to the requesting client.

Domain - Name of the network on your LAN. All inside interfaces will be on this domain. Entries without domain specified in the Hostname table are assumed to be in this domain.

This table lists all hostnames the DNS server recognises, and the IP address they resolve to.
The DHCP server will automatically fill in this table with all names found. Local network clients with static IP addresses need to be entered manually for the DNS server to resolve them.
