Hi,

Suppose i have configured IPv6 in my network and i have configured dual stack on my server. If any client from outside network tries contacting my server with the hostname then DNS will resolve which IP (IPv4 of IPv6) for my server. both of my server's ip will be there in DNS entry or it'll be one of them. If both then which ip (IPv4 or IPv6) it'll give.What is the selection crieteria for this in DNS.

Pls refer me few links also related to DNS entries for IPv6.

Regards,

It depends on what type of address is requesting the DNS lookup. If it is an IPv6 client requesting it then it will return the AAAA record. If it is an IPv4 client then it will return the A record.
