Hosted Public DNS
IU13 hosts a cluster of Infoblox DNS servers that provide authoritative resolution for WAN member public DNS zones.
If you would like to host a public DNS zone at IU13, please open a ticket to have the zone created in Infoblox, then work with your domain registrar to set the NS records for your domains to ns1.iu13.org and ns2.iu13.org
Note: These are not recursive resolvers. Don't point internal clients or forward requests from your DNS servers to these servers -- use the recursive WAN DNS forwarders instead.
