DNS is the switchboard for your domain.
A registrar manages the domain registration; DNS records tell browsers and services where to go. Your hosting provider gives exact CNAME, A, or other record instructions. Keep existing mail records intact—changing DNS blindly can interrupt email.
- Confirm you can access the registrar and DNS zone.
- Copy the hosting provider’s exact custom-domain instructions.
- Add only the required record and wait for propagation.
- Verify HTTPS and both the www and root-domain behavior.
- Document the setup and keep renewal/payment details current.
