Understanding DNS: Nameservers, A Records, and CNAME

DNS (Domain Name System) translates domain names into IP addresses so browsers can load your website.

Nameservers Nameservers tell the internet which DNS servers control your domain. When you point your domain to Neurax Host hosting, you update the nameservers at your registrar to ours. This tells the world to look at Neurax Host's DNS for all your domain's records. Propagation takes 24–48 hours globally.

Common DNS record types

A record Maps your domain (or subdomain) to an IPv4 address. Example: yourdomain.com β†’ 192.168.1.1 Use this to point your domain directly to a server IP.

CNAME record Creates an alias from one domain to another. Example: www.yourdomain.com β†’ yourdomain.com Use this for subdomains like www, mail, or shop.

MX record Directs email for your domain to the correct mail server. Example: yourdomain.com mail goes to mail.yourdomain.com Required for email to work correctly.

TXT record Stores text information. Used for:

  • SPF: Tells mail servers which servers are allowed to send email for your domain (reduces spam)
  • DKIM: Cryptographic email signature for deliverability
  • Google/domain verification codes

Managing DNS on Neurax Host Go to Domains β†’ My Domains β†’ Manage β†’ DNS Zone Editor. You can add, edit, or delete any DNS record. Changes take up to 30 minutes to propagate within Neurax Host's network and up to 48 hours globally.

Troubleshooting DNS Use a DNS propagation checker (e.g., dnschecker.org) to see if your records have updated worldwide. If your site is not loading after updating nameservers, verify the A record points to the correct server IP from your hosting account.
