Commonly Whitelisted Domains for pi-hole
Pi-hole is a great piece of software that will block almost every ad for all devices on your network. However by blacklisting some domains you can occasionally run into problems with unrelated services. Thankfully someone has created an excellent list of commonly whitelisted domains here as well as the related commands you need to run in order to actually whitelist them. I’ve re-produced the list below in case the original link stops working at some point.
