filtering port 53? Managing DNS and PTR on static IPs

I'm running an authoritative nameserver on a static IP I have been running for over a decade on Comcast services and it suddenly stopped responding. Is there a settings page somewhere in my account dashboard where I can configure or at least see the DNS entries and PTR entries for my block of static IPs?

Are you somehow silently filtering or redirecting port 53?
