DNS Basics

DNS maps your domain name to your hosting endpoints and email providers.

Recommended workflow

  1. Use A/AAAA records for website IP mapping.
  2. Use CNAME for aliases such as www.
  3. Use MX for incoming email routing.
  4. Use TXT for verification and sender authentication.

Connection Workflow

Connect your domain in controlled steps to reduce downtime risk.

Recommended workflow

  1. Decide if you manage DNS at KairoHost LLC nameservers or externally.
  2. Add required records for website and email services.
  3. Double-check record values, hostnames, and trailing dots when required.
  4. Save changes and wait for propagation before final validation.

Validation Checklist

  • Verify root domain and www resolve correctly.
  • Confirm SSL can be issued after DNS points correctly.
  • If issues continue, follow DNS troubleshooting steps.
