Frequently Asked DNS Questions

DNS - or domain name system - is a phonebook of every web address on the internet.
The DNS system translates human-readable domain names into IP addresses, which is then used to connect users to the content they’re looking for.
An IP address is a long series of numbers and symbols that only a computer can remember. Since we’re humans, we use readable language to visit a URL (ex: nexcess.net). DNS links the computer version of your domain (IP address) to the readable URL in your browser bar.

DNS lookup makes it possible for users to load your website globally. When an IP and domain are linked, your content is viewable to whoever finds it! It especially matters if you are registering a new domain name.
This process is usually straightforward. However, in the event of propagation errors, our free online DNS checker can quickly see if your new domain is properly linked up (or not).

There are several different types of DNS records; each type holds different information about the registered domain.
Learn more about domain name service records by clicking below.
DNS Records Overview

Enter your URL and use the dropdown menu to select your record type. Then click “look up” to test if your site’s DNS is working properly. If you are a current Nexcess customer, CNAME is the permanent host name for your site.

  • A - IPv4 address record
  • AAAA - IPv6 address record
  • CNAME - canonical name
  • MX - mail server
  • NS - name server
  • PTR - pointer record
  • TXT - any text-based information
  • SOA - state of authority record

If your DNS isn’t working, your website will not load. Global DNS is the critical glue that keeps websites online and connected.
