To change the local domain name, type option 12 on the Configure TCP/IP menu.
The Change TCP/IP domain information display is shown in Figure 16.
Notes:
1. Changes that you make using the Change TCP/IP domain information
(CHGTCPDMN) command take effect immediately.
2. The local domain name is used by many applications including PING. PING
appends the local domain to a host name if a domain is not specified or if a
period (.) does not appear at the end of the specified host name.
Domain Name System (DNS) Server
The conversion from host name to Internet address can be performed by using the
host table on the local system or by defining a Domain Name System server, or
DNS server.
In large networks with large host tables, it is more convenient to have DNS servers
than to have a complete copy of the host table on every host in the network.
A DNS server maintains the host table for an entire TCP/IP domain. This prevents
each single host from having to maintain its own local host table.
You can configure your server to use both a DNS server and your local host table,
but they are not mutually exclusive. You can also specify whether the domain
name server or your local host table is searched first.
For more information about how the Domain Name System works and how to
configure a DNS server, see DNS
