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.
rDNS won’t really help with that, it’s just a DNS lookup that ties your IP to a hostname, typically used for mail server spam controls.
I’m desperate.
Have you done any traceroute runs when the issue is happening to try and diagnose where the routing issue is occurring?
