Domain records tell browsers and mail systems where to find your services. A nameserver change can affect the website, email, verification records, and other services, so collect the current DNS configuration before editing it.

Before changing DNS

  1. Confirm the correct document root and hosting destination with your provider.
  2. Record the existing nameservers and DNS records, especially MX, TXT, and CNAME records used for email and verification.
  3. Ask whether your provider expects you to change nameservers or only specific records.
  4. Plan for DNS propagation. Some visitors may continue seeing cached records for a while.

Make and verify the change

Apply only the records your provider specifies. Do not replace all nameservers unless you understand where the rest of your DNS zone will be hosted. After the change, check the website over HTTPS and test sending and receiving email.

If email stops working, compare MX and TXT records with the values from your mail provider. Avoid deleting records you do not recognize until you know what service uses them. Contact your domain registrar or host with the domain name and the records in question; never send account passwords.
