What is DNS?

DNS (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 are then used to connect users to the content they’re looking for.

How does propagation work?

DNS propagation connects a website's address across the internet. First, DNS changes are made to the primary server for the domain name. The updated record is sent to all other servers globally, making it available on the internet.

How do I do a DNS lookup?

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 hostname for your site.

What DNS record should I look up?

There are several different types of DNS records; each type holds different information about the registered domain

A
The IPv4 address (A) record connects your domain to your hostname IP address. It “names” the server that hosts your website, using the legacy IP address system.
AAAA
The IPv6 address (AAAA) record connects your domain to a next-gen IP address. It also “names” the server you use to host your website.
CNAME
The canonical name (CNAME) record points an alias domain name to your correct domain name. If a user typed in example.com, it would redirect to www.example.com.
NS
The nameserver (NS) record identifies which server created the original DNS record. It shows the correct server path for the website being typed into the browser.
MX
The mail exchange (MX) record directs any incoming mail sent to an email address with your domain to the proper mail server in order to deliver it to your inbox
TXT
The text (TXT) record allows you to include human-readable notes about your domain. TXT is commonly used to verify ownership, a company name, or email credibility.
SOA
The state of authority (SOA) record shows ownership information for a domain and its last update. It also specifies propagation rules (DNS zones) to sync servers.
PTR
The pointer (PTR) record is a resolver between an IP and domain name. Known as reverse lookup, it identifies a domain associated with an IP address.
SPF
The sender policy framework (SPF) record confirms the authenticity of email sent from your domain. Without it, a server may consider it spam, phishing, or spoofing.

Why is DNS lookup important?

If you’ve recently switched hosting providers or started a new website, the first few days are a critical time for DNS propagation. If your DNS isn’t working, your website will not load. Global DNS is the critical glue that keeps websites online and connected.
