All,

I have loaded DDWRT on a small router and I am having the issue as follows.

I have set an IP for a FQDN as follows.

listen-address=127.0.0.1
listen-address=::1
address=/FQDN/XXX.XXX.XXX.XXX
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.

It is these clients that I am testing with and to make testing valid I need to 
leave them in out of the box condition.

I need to have the Router reply to the IPv6 A record query with my fixed 
address and I haven't been able to figure out how to force it to do so.

Anyone who has already tackled this and could enlighten me from this list?
