DNS A Record

Sitecheck Team

Maps a hostname to an IPv4 address.

An A record maps a hostname (like www.example.com) to an IPv4 address. It is one of the most common DNS records used to route traffic to a server.

Why it matters: Incorrect A records lead to downtime or traffic going to the wrong server.

Quick tips:

  • Keep TTL values reasonable for planned changes.
  • Use multiple A records for basic load distribution.
