DNS on Cloudflare

Cloudflare runs fast authoritative DNS for your domain.

📖 Key ideas

  1. A record maps a name to an IPv4 address; AAAA to IPv6.
  2. CNAME points one name to another name.
  3. MX records route email; TXT records verify ownership (SPF, DKIM).
  4. Proxied records (orange cloud) go through Cloudflare; DNS-only (grey) do not.
  5. TTL sets how long resolvers cache a record.
💡 Real-life example: Like a phone directory: you look up a name and get the number to call.
A recordName to IPv4 address
CNAMEName to another name
MXMail server record
