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.

Not sure if any seasoned sysadmin actually use uceprotect blocklist in their network though, so you shouldn't lose sleep over that one.

Some light reading related to uceprotect:
