How to Prepare Network Services for IPv6 Support

1. Update the following network services to support IPv6:

   • Mail servers

   • NIS servers

   • NFS

     ---

     Note - LDAP supports IPv6 without requiring IPv6-specific configuration tasks.

     ---

2. Verify that your firewall hardware is IPv6 ready.

   Refer to the appropriate firewall-related documentation for instructions.

3. Verify that other services on your network have been ported to IPv6.

   For more information, refer to marketing collateral and associated documentation for the software.

4. If your site deploys the following services, make sure that you have taken the appropriate measures for these services:

   • Firewalls – Consider strengthening the policies that are in place for IPv4 to support IPv6. For more security considerations, see Security Considerations for the IPv6 Implementation.

   • Mail– In the mail exchanger record (MX record) for DNS, consider adding the IPv6 address of your mail server.

   • DNS– For DNS-specific considerations, see How to Prepare DNS for IPv6 Support.

   • IPQoS – Use the same Diffserv policies on a host that were used for IPv4.

5. Audit any network services that are offered by a node prior to converting that node to IPv6.
