|
Display IPv6 information through NIS |
Displays the IPv6 information through NIS+ by using the nismatch command. | |

How to Display IPv6 Name Service Information
In this procedure, you use the nslookup command to display IPv6 name service information.
-
On the command line, type the following command:
% /usr/sbin/nslookup
The default server name and address appear, followed by the nslookup command angle bracket prompt.
-
To see information about a particular host, type the following commands at the angle bracket prompt:
>set q=any >host-name
-
To see only AAAA records, type the following command at the angle bracket prompt:
>set q=AAAA
-
Quit the command by typing exit.
Example—Using nslookup to Display IPv6 Information
% /usr/sbin/nslookup Default Server: space1999.Eng.apex.COM Address: 120.46.168.78 > set q=any > vallejo Server: space1999.Eng.apex.COM Address: 120.46.168.78 vallejo.ipv6.eng.apex.com IPv6 address = fec0::9256:a00:fe12:528 vallejo.ipv6.eng.apex.com IPv6 address = 2::9256:a00:fe12:528 > exit |
How to Verify That DNS IPv6 PTR Records Are Updated Correctly
In this procedure, you use the nslookup command to display PTR records for DNS IPv6.
-
On the command line, type the following command:
% /usr/sbin/nslookup
The default server name and address display, followed by the nslookup command angle bracket prompt.
-
To see the PTR records, type the following command at the angle bracket prompt:
>set q=PTR
-
Quit the command by typing exit.
Example—Using nslook to Display PTR Records
% /usr/sbin/nslookup Default Server: space1999.Eng.apex.COM Address: 120.46.168.78 > set q=PTR > 8.2.5.0.2.1.e.f.f.f.0.2.0.0.a.0.6.5.2.9.0.0.0.0.0.0.0.0.2.0.0.0.ip6.int 8.2.5.0.2.1.e.f.f.f.0.2.0.0.a.0.6.5.2.9.0.0.0.0.0.0.0.0.2.0.0.0.ip6.int name = vallejo.ipv6.Eng.apex.COM ip6.int nameserver = space1999.Eng.apex.COM > exit |
How to Display IPv6 Information Through NIS
In this procedure, you use the ypmatch command to display IPv6 information through NIS.
On the command line, type the following command:
% ypmatch host-name ipnodes.byname |
The information about host-name displays.
Example 15–1 Example—Using ypmatch to Display IPv6 Information Through NIS
% ypmatch vallejo ipnodes.byname fec0::9256:a00:20ff:fe12:528 vallejo 2::9256:a00:20ff:fe12:528 vallejo |
How to Display IPv6 Information Through NIS+
In this procedure, you use the nismatch command to display IPv6 information through NIS.
On the command line, type the following command:
% nismatch host-name ipnodes.org-dir |
The information about host-name displays.
Example 15–2 Example—Using nismatch to Display IPv6 Information Through NIS+
% nismatch vallejo ipnodes.org_dir vallejo vallejo fec0::9256:a00:20ff:fe12:528 vallejo vallejo 2::9256:a00:20ff:fe12:528 |
How to Display IPv6 Information Independent of Name Service
On the command line, type the following command:
% getent ipnodes host-name |
The information about host-name displays.
Example 15–3 Example—Using getent to Display IPv6 Information Independent of Name Service
% getent ipnodes vallejo 2::56:a00:fe87:9aba vallejo vallejo fec0::56:a00:fe87:9aba vallejo vallejo |
