What is the dnsserver?
DNS means Domain Name System which helps to transfer ip address to domain name and domain name to ip addresses.It plays vital role in internet technology.For example,if you provide domain name like Google.com it convert the domain name into particular ip address.If you provide the ip address like 74.125.239.9 the domain name server will search for the particular website and display on your browser.DNS consist of many resource records.Some of them are A record,CNAME record,DNAME record etc., You can check domain to ip ,Ip to domain and DNS query using the site Whoisxy.com
The dnsserver is a process forked from the squid process in order to resolve IP addresses from domain names. This is necessary because the gethostbyname() function blocks the calling process until the DNS query is resolved. Squid must use non-blocking I/O at all times, so DNS lookups are implemented external to the main process. The dnsservers do not cache DNS lookups, that is implemented inside the Squid process.

If you have reason to use the old style dnsserver process you can build it at ./configure time. However we would suggest that you file a bug if you find that the internal DNS process does not work as you would expect.
