Do you have a list of the most common social media sites and which hostname(s) and/or IP address(es) are associated with them? Maybe a sticky at the top of the Parental Controls forum? I have several already, but am missing info for services such as Instagram and SnapChat. Streaming services (Netflix, Hulu, Amazon Video, etc) would be great, too. The list might be too large for a post, but a resource somewhere would be very helpful.
