What this means in practice is that your local name server doesn't have all the information for, say, but it can figure out who to ask about it and find out for you when you make a request.At the top of the DNS hierarchy are 13 root name servers, which contain name server information for all of the generic top-level domains such as and as well as country-specific DNS addresses such as or

The name servers for each of these top-level domains contains name server information for domains within that top-level domain.So the name server for will contain information about but will not contain information about uk.As of this writing, the authoritative location for the root hints file is configure a secondary zone while using the MMC to manage the DNS server, select Action | New Zone, and select secondary when prompted for the zone type.A caching-only server does not require any DNS zones to be configured or loaded because it does not have any information that is served to the rest of the Internet.

It is wise to check that the root server hints file is up to date before deploying the server into production, however; this information, stored in systemroot\system32\dns\cache.dns, contains pointers to the root DNS servers where your server will begin all queries in the absence of other, more specific information.If the servers don't list my server as a name server for the domain, then no hosts on the Internet will know to ask my server for information about Any time you register a new domain, or move a domain's name servers from one set of hosts to another, you have to work with your domain name registrar to make sure that DNS servers on the Internet will know to ask your DNS server for information about your domain.When a DNS server learns a new piece of information as the result of a query for a client machine, it will cache that information for a while—the actual cache time is specified by the server that provided the authoritative information.During that time, client machines that ask for that particular piece of information will be given the cached information; the DNS server will perform no further queries to find out if the information has changed until it deletes the cached entry when the time to live (TTL) expires or the entire cache is cleared.Your name server will have to contact the server that contains the information for uk.
