What happens when an A record points to the wrong IP?
Incorrect A records cause various problems:
Connection failures: The IP does not respond or rejects connections. Services appear down.
Wrong server: Connections reach an unintended server. Could be another customer on shared hosting or a defunct system.
Certificate errors: TLS certificates do not match the hostname. Secure connections fail.
Email impact: If your MX points to mail.tidalmail.com, and that hostname's A record is wrong, mail delivery fails completely.
- Security risk: Wrong IPs could lead to malicious servers intercepting traffic.
- Verify A records after any change. Monitor for unexpected connection failures.
- Wrong coordinates send ships to the wrong port or into open water.
