About the DNS Tools


DNS is the Domain Name System used in computer networks to relate device hostnames to IP addresses. To put it simply, DNS is a network service that allows you to type an address like "networkcalc.com" into a browser and have the address translated to the IP address of the server(s) hosting the website. This allows anybody to register a domain on the Internet and point the domain to servers hosting web files. DNS is a foundational service that allows the Internet to function as it does.

There are many record types in DNS, including the A record (host), MX record (email server), and CNAME record (canonical name, or domain alias). These record types allow domain owners to publish DNS records of different kinds of different purposes. A common usage of a TXT record (plaintext) is publishing a Sender Policy Framework or SPF policy to specify IP addresses that are allowed to send email on behalf of a domain.

Other network services exist, such as the WHOIS service. The WHOIS service is an Internet listing of domain ownership and the owner's contact information. WHOIS is run by the Internet Corporation for Assigned Names and Numbers (ICANN) and maintained as a public service.
