When I edit a dns zone in WHM. I am able to add new entry for A record. Basically create a subdomain then points to external ip. How do I delete some subdomains? I don't find any options. When I try delete a dns zone, it deletes the entire zone, that is not what I want. Please see pictures for more detail
Make the that entire entry blank say for example if you create sub domain named test.yourdomain.com then remove all entry made against host name test which will be a A record and once cleared you go down and simply click on save and this should solve your issue.
