This section provides procedures to display IPv6 name service information.

Displaying IPv6 Name Service Information Task Map

How to Display IPv6 Name Service Information

In this procedure, you use the nslookup command to display IPv6 name service information.

1. 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.

2. To see information about a particular host, type the following commands at the angle bracket prompt:

   >set q=any >host-name

3. To see only AAAA records, type the following command at the angle bracket prompt:

   >set q=AAAA

4. 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.

1. 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.

2. To see the PTR records, type the following command at the angle bracket prompt:

   >set q=PTR

3. 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 2–1 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 2–2 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 2–3 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
