Quote:

The Domain Name System (DNS) is a hierarchical naming system built on a distributed database for computers, services, or any resource connected to the Internet or a private network. Most importantly, it translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.
An often-used analogy to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses.

Note that when you want to join a domain name that does not exist, you are redirected to an OpenDNS page that serves as a search engine (this is thanks to the ads found on this page OpenDNS earns money).

Is it a good search engine? Last time I saw it, the content was a list of very vaguely related sites, presumably paid for by the sites. For me this is broken behaviour and I would rather get a 404 in a web browser than useless advertising.

However, contrary to what one can read everywhere, OpenDNS is faster than the DNS of my ISP. Using the dig command lets put this into evidence.

OpenDNS servers do respond quickly but generally not as quickly as the best ISP DNS servers. The test shown is only applicable for that ISP so has limited relevance for most readers of the article.

Public DNS server response times can be tested via http://www.willemijns.com/dns.htm.

A script for testing response times of ISP, OpenDNS and Level3 public DNS servers is at http://pastebin.com/U0VBG96q. It has BSNL (Indian ISP) server IP addresses hard-coded so they need to be manually changed to the user's ISP's.
