rDNS, how? (feddit.dk)

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.

Depending on your isp, you may be required to have a business class plan with a static ip. I went through something similar years ago for my business. This is old documentation for Verizon, but it's a hint.
