Hello -<br />
<br />
We have a DNS company.com. &nbsp;We will have several names @.company.com (they may be our customers) We have our DNS hosted with a vendor. &nbsp;We want to make sure our customers remain as hidden or private as possible...Can someone/anyone easily do some sort of query on a DNS to list all the @.company.com names? &nbsp;Sure, someone could just start typing name.company.com...but just doing a sanity check to see if someone wanted to find out all the different names.company.com, it's not that easy.<br />
<br />
Thanks.

Can someone query a DNS for all the A records?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
