Step 9
To add an “A” Resource Record (RR) to a forward zone (domain) and map a name to an IP address,
enter the
zone
command:
nrcmd> zone the.net. addRR bobslake-nas-02 A 172.21.10.18
@ IN NS onionring.the.net.
@ IN SOA onionring.the.net. netadmin.the.net. 56 10800
3600 604800 86400
Dynamic Resource Records
Static Resource Records
aurora IN A 172.21.100.100
bobslake-nas-01 IN A 172.21.10.10
bobslake-nas-02 IN A 172.21.10.18
doc-2610-01 IN A 172.21.10.13
doc-3810a-01 IN A 172.21.10.14
doc-3810d-01 IN A 172.21.10.15
doc-AS5850-01 IN A 172.21.10.11
doc-core-01 IN A 172.21.10.5
doc-core-02 IN A 172.21.10.6
doc-core-03 IN A 172.21.10.7
(truncated for brevity)
In the previous example, the
zone
command:
Creates an A record for the.net
Assigns the IP address 172.21.10.18 to the router bobslake-nas-02
Step 10
To reload the server to make all IP assignments or changes take effect, enter the following command:
nrcmd> server dns reload
Note
Reload all changes into the DNS database, so that the changes can be resolved
upon lookup.
