I would guess the Canadian government employ people to manage social media for various departments. They may use TikTok, both to view content to understand for research or to post in order to promote their services/role/existance. Similarly I might imagine they have Twitter, Facebook, Instagram and other apps which facilitate spreading information.

I think generally you don't get a choice when it comes to DOCSIS equipment. You can't just connect up your own (or at least no to Virgin Media's network)

Generally not by default, but that can vary by manufacturer. You can just download one of the many available from the Play Store.

Try it using an IPv6 address ;)
