@ -547,4 +547,8 @@ AFS uses the following DNS entries::
_afs3-vlserver._udp.openstack.org. 300 IN SRV 10 10 7003 afsdb01.openstack.org.

Be sure to update them if volume location and PTS servers change.
Be sure to update them if volume location and PTS servers change. Also note
that only A (IPv4 address) records are used in the SRV data. Since OpenAFS
lacks support for IPv6, avoid entering corresponding AAAA (IPv6 address)
records for these so that it won't cause fallback delays for other
v6-supporting AFS client implementations.
