Manage SOA Records on AlexHost VPS for Reliable DNS

Why manage SOA records on AlexHost? SOA records define critical DNS zone details, ensuring proper domain functionality.

What is an SOA Record?

An SOA record contains important information about the domain, including:

1. Primary Name Server: The primary DNS server responsible for managing the domain.
2. Responsible Party: The email address of the person responsible for managing the domain (formatted as admin.example.com, which means admin@example.com).
3. Serial Number: The version number of the DNS zone file. This number increases with every update to the DNS zone, signaling to other DNS servers that the zone has changed.
4. Refresh, Retry, Expire, and TTL Values: These values define how often DNS servers should refresh the zone and handle failures.

How to Check an SOA Record

You can check an SOA record using various tools, such as the dig command or online DNS lookup services.

1. Using the dig Command

The dig command is a DNS lookup utility available on most Linux and macOS systems. To check the SOA record for a domain, use the following command:

The output will display the SOA record for the domain, including the primary name server, serial number, and other details.
