<p class="MsoNormal">The if a WiFi UE makes an A record query
over IPv4 transport all is well and I am able to force
connection to the XXX.XXX.XXX.XXX node I am testing. The GTM
serving the DNS has many geographic nodes and within regions
many nodes served round robin. The problem is when dual stack
clients attach they prefer IPv6 and will send their A record
query out over IPv6 and get another IP from the GTM pool. This
is correct behavior the devices do both AAAA and A record
searches over IPv6.
