      Dumb question for @bnrstnr why not setup PiHole individually for each of your friends and families networks rather than dealing with a public DNS for everyone.

      How would I set it up individually for everybody? None of my friends or family has a raspberry pi, server, or anything that could run it. I use a $2.50 instance on vultr.

      They'd need one of those thing each for themselves to run it individually.

      Scott's post points out why that's likely a less than desirable solution.

        @bnrstnr Dash beat me to the answer.

        But yeah, you'd setup a Pi in each person's network and then configure their local DNS to use the PiHole.

          The occasional complaint is nothing something I would worry about - especially when you're doing nothing wrong - I wouldn't change anything from what you have today. it's way to flexible and low cost to worry about changing.,

            That's the way I'm leaning, too. I might try to do some geo-blocking, but I doubt I'll ever get to it. Especially since nobody here has seen this before on their piholes.

              I don't think anyone else here is using PiHole as a public DNS. . .

                  That's non-trivial for home users or really small SMBs. You need somewhere to run that and most people don't have servers.

                    Had the same thing happen to my Vultr Pi-Hole.. I deleted the server for the time being.. and may not rebuild.

                        Correct.. the notice came in over the weekend.

                          Right, totally different. One is being told you have an open port, which is essentially guaranteed to happen as Vultr does that every few days. The other is very unlikely, an actual attack.

                          Everyone on Vultr gets the one. When we said that no one else has had this happen, you didn't have it happen either.

                            You can limit the access to port 53 to the locations (Homes and offices) that use your Pi-Hole in Vultr. That is how I had it on Google DNS.

                                @gjacobse Vultr is seeing the traffic spike on your instance, to levels way beyond what is normal and likely for a sustained amount of time.

                                Thus they are telling you to fix whatever is wrong or they are shutting you down.

                                  I never got htis obsession with making public Pi-Hole systems.
                                  No one is going to go to all the trouble to override their cellular settings to use the Pi-Hole when roaming.

                                  Just setup something at home and move on.

                                    @JaredBusch that was kind of my point.

                                    How much value is there in doing this, really?

                                          Why do it at all then? I mean sure, we are at home "most" of the time. But you still want it when not at home.

                                            I never got htis obsession with making public Pi-Hole systems.
                                            No one is going to go to all the trouble to override their cellular settings to use the Pi-Hole when roaming.

                                            Just setup something at home and move on.

                                            I do 🙂

                                            You aren't the majority.

                                            @JaredBusch that was kind of my point.

                                            How much value is there in doing this, really?

                                            Why do it at all then? I mean sure, we are at home "most" of the time. But you still want it when not at home.

                                            Because this would be comparable to doing it for a business. Run your house like you would run a business.

                                            PiHole is designed with the intention of being used on a LAN. Not as a public DNS server. . .
