Resolver

It then returns its results to the DNS resolver; assuming it has found a result, the resolver duly caches that result for future use, and hands the result back to the software which initiated the request.

The resolver, or another DNS server acting recursively on behalf of the resolver, negotiates use of recursive service using bits in the query headers.

When using encrypted DNS, you are essentially placing your trust in the DNS resolver to handle your data responsibly.

Historically, other directory services preceding DNS were not scalable to large or global directories as they were originally based on text files, prominently the HOSTS.TXT resolver.

However, with only authoritative name servers operating, every DNS query must start with recursive queries at the root zone of the Domain Name System and each user system would have to implement resolver software capable of recursive operation.

If a stub resolver queries the caching nameserver for the same record before the TTL has expired, the caching server will simply reply with the already cached resource record rather than retrieve it from the authoritative nameserver again.

If the cache can provide the answer to the request, the resolver will return the value in the cache to the program that made the request.

If the cache does not contain the answer, the resolver will send the request to one or more designated DNS servers.

In addition the suite contains various administration tools, and a DNS resolver interface library.

Some resolver implementations use TCP for all queries.
