An internet service that translates domain names into IP addresses. This is the core reason that you can refer to a website by its domain name and not have to remember its IP address.
Your DNS can be managed in a number of different ways. One common method is through your domain name service (not to be confused with domain name server).
DNS- Domain Name System
Domain Name – example: Element74.com
IP Address- A unique string of numbers separated by periods that identifies each computer using the Internet Protocol to communicate over a network.
Nameservers- Web server that has DNS software installed and managed by web hosts designed to specifically manage domain names
TLD Nameservers- Terms that apply to the last part of a domain (.com,.org,.ca,.net)
CNAMES- Alias names that refer to a domain
A Records- These are records that assign a name to an ip address. These help you to identify a website with a domain name instead of identifying it by an IP address
MX Records- These are records that redirect emails to designated mailboxes. They also have different priority settings
Txt Records- Records that hold free form text of any kind. Historically, these records have been used to contain human readable information about a server, network or data center.
Sub Domains- An internet domain which is part of a primary domain (web-mail.element74.com)
