Hi MB,
if you don't apply a DNS profile to your Virtual Server, your F5 wouldn't care about A, AAAA or even combined A & AAAA queries. Only the payload size of the DNS query / response would matter in this case...
Have you already captured the ingress / egress traffic of your F5 to see if the F5 quickly forwards the DNS request/responses and/or if the client eventually tries to use DNS-over-TCP and needs to wait for TCP timeouts (e.g. DNS payload >= 512 bytes)?
Cheers, Kai
