System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP)

Enabling a Client to Use IPv6

You can enable a client to use IPv6 by using the following procedure.

How to Enable a Client to Use IPv6

  1. Become superuser.

  2. Edit the /etc/nsswitch.conf file.

  3. Add the new ipnodes source and specify the naming service, such as LDAP.


    ipnodes: ldap [NOTFOUND=return] files

    ipnodes defaults to files. During the transition from IPv4 to IPv6, where all naming services are not aware of IPv6 addresses, you should accept the files default. Otherwise, unnecessary delays might result during the resolution of addresses.

  4. Save the file and reboot the machine.

    Because the nscd daemon caches this information, you must reboot the machine.
