Masking domain IP over redirection
===

I have domain.com and redirecting its subtomain sub.domain.com to an dedicated server's IP: 0.0.0.0

When I ping sub.domain.com it gives me 0.0.0.0 - how to mask it?

@domain.com - its hosted at virtual host, and my 0.0.0.0 IP is on dedicated server. Its for online gaming
