Part 2: Learn DNS

DNS records connect the domain to websites, email systems, verification services, and other network resources.

Chapters

  1. Delegation and External Nameservers
  2. DNS Record Types
  3. Root Domains and Subdomains
  4. TTL, Caching, and Propagation
  5. DNS Troubleshooting

Make one DNS change at a time, record the previous value, wait for the authoritative answer to update, and verify the result before changing another layer.

All record-editing examples in this category are performed at the external authoritative DNS service, not at the registration platform.
