Only one host name can be defined to this router.
Only one domain name can be defined to this router.
Up to 3 name servers can be specified.
Name server and domain name cannot be defined unless host name of this
router is specified.
Domain name cannot be specified unless name server is specified.
localhost cannot be defined as host name.
Set the DNS server's IP address (dns resolver nameserver) correctly. If the
DNS server's IP address is not set correctly, it will take a long time to detect
the interruption in communication with the DNS when the host name is
referred, disrupting operation. (The time required to display a log in prompt
increases when remotely connected to this device via telnet).
The nslookup command can be used as a method to confirm the DNS server. If the
"nslookup-retry=1" command, which is the IP address of the DNS server for the
host name to be referred, is executed, the host information specified as follows
will be displayed when the DNS server's IP address is correct.
Server: Host name in the DNS server.
Address: IP address in the DNS server.
Name: The designated host name.
Address: Designated host's IP address.
If the IP address of the DNS server is not correct, the following indication will be
displayed.
*** Can't find server name for address, the IP address of the DNS server: Timed
out.
127.*.*.* cannot be specified as IP address.
Class D and class E addresses cannot be specified as IP address.
Up to 255 characters can be used for host name and domain name. Up to 80
characters can be used for browser.
It is not possible to refer to the AAA query information by using the IPv6. The
AAA query information is referred by using the IPv4.
If this command is inputted in the cases where changes are made on the IP
routing protocol information, the IP multicast protocol information, and the

IP routing protocol information, IP multicast routing protocol information,
and MPLS information are reflected to the operation.
To effectuate the relay function, it is also necessary to effectuate the DNS
resolver function.
