Zone transfers internally should be allowed to help admins do their jobs. More and more services on the Internet today are taking advantage of CDNs and multiple instances that leverage GeoDNS or other site aware approaches to provide local responses to globally distributed clients. Query one of them for a name. However, this is off by default, which can lead to old or out-of-date data in DNS, including registrations for systems that you shut down ages ago. I strive for under 25ms, but under 50ms is good enough.

More and more services on the Internet today are taking advantage of CDNs and multiple instances that leverage GeoDNS or other site aware approaches to provide local responses to globally distributed clients. If the zone is single label name, such as 'domain' instead of the proper minimal format of 'domain. If it doesn't get a response, it removes the first one from the eligible resolvers list and goes to the next in the list. Allowing zone transfers externally, and not allowing them internally Zone transfers enable a DNS server to provide the entire set of records for a namespace in response to a single query. The Zone must be configured to allow updates. The following has more information on how to do that: It's just a single name. Avoiding these nine pitfalls helps to make sure that happens. Keeping DNS clean makes it easier to find resources and troubleshoot issues. This is the reg entry to cut the query to 0 TTL: Keep in mind, for the most part it automatically works "out of the box" without much administrative overhead. When you run AD integrated DNS, you have the option to permit dynamic updates and require that they be secure … meaning authenticated by domain members. Due to this excessive Root query traffic, which ISC found from a study that discovered Microsoft DNS servers are causing excessive traffic because of single label names, Microsoft, being an internet friendly neighbor and wanting to stop this problem for their neighbors, stopped the ability to register into DNS with Windows SP4, XP SP1, especially XP,which cause lookup problems too , and Windows For client machines, if a client is not joined to the domain, and the zone is set to Secure, it will not register either. Far too often, admins opt to skip out on setting up the in-addr. But on the outside, allowing zone transfers makes it far too easy for an attacker to do reconnaissance. Forwarding far, far away Just as you want to keep DNS servers close to clients, you want your DNS servers to resolve as close to themselves as possible. For joined machines, this is default. In the end it comes back to itself and then attempts to register. Registration attempts causes major Internet queries to the Root servers. The basic one is the DNS address on the client, as Meinolf said. Sign in to vote Pei Wai, As mentioned, there are a number of reasons a machine may not register. When one DNS server in an authoritative zone needs to update its full zone file, or when an admin needs to check on things, that makes it easy to see the entire zone. It will not go back to the first one unless you restart the machine, restart the DNS Client service, or set a registry entry to cut the query TTL to 0. The DNS Client service does not revert to using the first server
