Re: $20,000 a day?
said by TamaraB  :said by Matt :... Where do you think the caching DNS server gets it's answers? Directly from the ROOT servers, totally bypassing your ISP. The root server points you directly to the authoritative DNS server of the domain you want to access. Bob You're correct. I was confusing a caching name server with a name server that is authoritative for a specific zone. If you have a zone configured, your name server requires a forwarder for all zones it's not authoritative for.
I run DNS for my LAN, which was causing my confusion. |

I run MS DNS at home and if you configure a forward lookup zone (like I have for my LAN, universe.local) and don't configure forwarders, it will return an NXDOMAIN result for any domain that isn't universe.local. |

| You just need to check the root hints list
I have an MS dns server at home as well and didn't set any forwards and just rechecked the root hints
and internal dns for my website works aswell as resolving external
and I have reverce and forward zones but not forwarders |

The correct distinction is forwarding DNS server (dnsmasq found in most residential gateway appliances) vs recursive dns server (BIND,windows, etc can do both), which takes a query, starts with the root servers, and keeps going until it ultimately gets the answer it wants.
dnsmasq in its default setting will forward queries to another server or servers. one very useful feature of dnsmasq is that you can have it simultaneously forward to multiple servers and return whatever result comes back fastest.
