      The Maxmind database is, in the most charitable way possible, not accurate. IP's are horse traded between entities freely.

      You will need to whitelist what you need to, Maxmind isn't going to fix their free offering.

        104.244.74.128

        That is owned by frantech, and sure its a block used by VPS in the Luxembourg DC.. as stated by jwj already - geoip is not something I would call close to accurate ;) The problem is the company is US based, but they use parts of their IP space in different parts of the world..

          Thanks guys. That is good to know. I had no idea geoip was such a moving target.

            IP space moves all the time!! We have been selling off some our space, and its moved all over - transferred to ripe.. But yeah that for sure could still be listed that its out of the US, when its not..

            Also currently got a project running were we assigned some space that will be used in the US, but its being advertised out of a ripe ASN number, which could look like its out of the EU vs US, etc..

            Its moving target to be sure - and can never be sure if the database is even updated, or was ever correct ;)

              Another example. The amazon store app on my (and other families iPhones and iPads) hits a AWS instance that is, according to MaxMind, in china. Go figure...

                Well AWS does have 2 location in china - so its possible, wouldn't make a lot of routing sense unless your in that part of the world..

                https://www.amazonaws.cn/en/about-aws/china/

                Whats one of these IP they are talking too? Just curious..

                GeoIP is slick when it works ;) But when it doesn't your like WTF are these idiots thinking ;) We had a /24 in our space that geoip said was in Vietnam... Have no idea where they ever got that idea from, sure and the F never used it there, sure and the F were not advertising it out of there.. Tried for ever to get it fixed up, They say they update ever 2nd tuesday of the month or something.. We stopped using that space completely - use to be the IP used by proxy out of FL location.. So users hitting that IP would get stuff like they were in vietnam, banks would would prevent users from logging in, etc.. it was PITA ;)

                  54.222.63.5
                  54.222.60.218
                  54.222.60.25

                  Amazon app works if that is blocked, but it will hit those every three or four days trying to update something.

                        Thanks for having a think about it. I really should get rid of those outbound geoip blocks. Blunt force weapon that solves nothing useful for me. Maybe block something outbound that is more targeted. ET Comp or one of the firehol lists as a canary...

                        Better end point security wouldn't hurt for me either. Need to not be so lazy ;)

                        Thanks again!

                          You sure those are AWS? I can not find those prefixes in there published IP blocks

                          https://ip-ranges.amazonaws.com/ip-ranges.json

                          I see ones close.. But not any that those IPs fall into exactly.. Maybe missing??? So for example I see a

                          54.222.64.0/23 but I don't see anything that would cover 54.222.63

                            I think they are, could they be gstatic addresses? I do miss Pi-Hole, could answer the question in a second...

                              That is this
                              Amazon EC2 BJS Prefix

                              So its not actual AWS ;)

                              dl.amazon.cn points to it for example..

                              Your not anywhere near china are you? Curious why you would be going there to be honest..

                                Wonder what it's after from that? Profile data? It's the problem with encrypting EVERYTHING. If it's not personally identifying why is it encrypted? Can't sniff to see what it is...

                                    That 218 IP is
                                    www.amazon.cn. 1833 IN A 54.222.60.218

                                      Curious. Some jurisdictional thing? Maybe they have just F'd up their load balancing.

                                            Problem is, you can't mix them right? So for an alias-permit, there is no good solution to add some IPs to a geo-range or is there and if how? I guess you have to create your own URL-Alias somehow.
