Domain Name Systems (DNS)
Overview
The Domain Name Systems (DNS) is the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.
Objective
- Address records and Mail Exchange records need to be kept up to date to ensure that access to your domain is maintained. Incorrect Mail Exchange records will result in sporadic or failed delivery of emails to your business’s mail server, while incorrect Address records will prevent access to your website.
