      What if I setup a dynamic DNS client on a computer, and have it update to my domain, say name.domain.com then have a script nslookup the domain name and update the firewall rules?

        Would it not be easier to skip the DDNS parts and just have a script send the IP address directly?

              Use Python or PowerShell

                        Hence Python, the universal system automation language.

                          True, could be done just like on Linux.

                            What OS are you going to be installing pi-hole in?

                            Liked the idea so just started working on the script, resolving the dynamic dns name and logging it and comparing it to the current ip is done. Just need to target your OS of choice to test the creation/destruction of the firewall rules.

                            https://github.com/rodrigo-hissam/dns_to_ip_firewall_rules/blob/master/dns-to-ip-firewall-rules.py

                            Example:

                            ~/scripts/python$ python dns-to-ip-firewall-rules.py 
                            
                            Adding to firewall - TODO
                            mangolassi.it - 104.25.47.32 
                            
                            Adding to firewall - TODO
                            google.com - 172.217.1.238

                            #Log files created per host to store the previous ip for the comparison.
                            ~/scripts/python$ ls
                            dns-to-ip-firewall-rules.py  google.com  mangolassi.it  theverge.com
                            
                            # Re running the script to compare with logged ip
                            ~/scripts/python$ python dns-to-ip-firewall-rules.py 
                            
                            Same ip address nothing to do

                              I am not a scripter, nor do I play one on TV, but you can get your public IP using this:

                              curl ifconfig.co

                                            @romo This is f'ing brilliant! The downside is that now I HAVE to try this on Vultr. Anyone have a script to add more hours in the day?

                                            Btw, what's your frequency for running this in cron? Every 5 mins? 15mins?
