I'm helping my boss clean up our DNS records on Verizon and neither one of us is sure what to make of these. There are a couple records that consist solely of a semicolon. No record type, no address, no anything--it's just a semicolon.

Do these serve any purpose, or can we just remove those records?


Semicolons are part of the bind zone format. However, there is no way to know how your management tools are interpreting these records.

Many DNS providers require placeholders to specify a domain.com. I've seen *, @, and # used in various web-based DNS management tools.

I recommend contact your DNS provider for clarification as web-based DNS management tools differ.

  • From the linked document, a semicolon would seem to be a comment marker?

  • Semicolons are used for comments but there's no way to know how they are used in your web-based management tool. You need to ask your provider for details. Aug 11 '14 at 20:15
