We need to setup a DNS server on CentOS for IP V6 with the bridging option i.e any customer comes in this ISP, this bridging server will be decide if it is for IPv4 or IPv6 customer and accordingly forward the traffic to the newly installed DNS ( IP v6) or the existing DNS ( IP v4)
Pls bid whom so ever having prior skill on the same.
This is for an ISP scenario where there will be 20000 customers landing to the ISP.
Best Regards
