I have a domain that needs to use second level subdomain. I am curious why when I have the
@ A record and the blank A record a second level subdomain does not resolve. For example
subsubdomain.subdomain.domain.com is not resolving to the root domain records. In this example if I add
subdomain A record then that second level domain resolves.
Thanks for any clarification.
EDIT: This is using register.com as the DNS provider.
