I’m on at least 2 blocklists at this point for the crime of not having reverse DNS set up. I don’t know how rDNS works. No amount of reading Wikipedia is helping me understand what I have to do.
- I have a domain at a registrar which gives me bog standard DNS.
- I have Apache running on my network.
- I have PiHole running on my network.
My understanding is that rDNS is not set up at my registrar, but somewhere in my network. What do I do?
Thank you for your time.
You are right, more specifically in case anyone is curious it usually has to be whomever owns the public IP addresses because that is who would own the reverse zone for that IP block according to the internet root dns servers in most circumstances. In OPs case you are probably right, this is probably the VPS provider but not always.
