: Subdomain connection time out I created a subdomain, but the connection just times out. I checked the zone file and I have one (A)ddress record with a wild card (*) pointing to my server's
I created a subdomain, but the connection just times out. I checked the zone file and I have one (A)ddress record with a wild card (*) pointing to my server's IP address. As far as I understand, that's the correct setting in the zone file to make sure all subdomains point to my server. Is there something else I am missing? What are ways to troubleshoot this issue?
I have used trace route, ping, and dig to find out more information.
ping -> timeout (loss)
trace route -> no conclusion
dig -> tells me that the domain does have an address

The exact rules for when a wild card is match are specified in RFC 1034, but the rules are neither intuitive nor clearly specified. This has resulted in incompatible implementations and unexpected results when they are used.
Your DNS should look like this
A NAME (blank or @ on some systems) FQDN domain.com IP
A NAME www FQDN domain.com IP
A NAME subdomain FQDN subdomain.domain.com IP
Try and avoid a wild-card in the DNS.
