I am glad YouTube hasn't blocked me even though I only access it with ytdl-sub nowadays, as I have had the same non-static IP for over 2 years now.
I am honestly assuming my ISP noticed I am self hosting stuff that only I can access and gave me a free static IP, because that shit hasn't rotated even after a half dozen power day long power outages, and multiple day long service outages.
Not to mention the dozens of times I have had to reboot my modem for various reasons.
I have no way to check, but i honestly think it survived a modem replacement in my early days of self hosting (modem partially fried itself in an... interesting fashion).
Can confirm it happens even with residential IPs recently, good thing I don't have static or 'sticky' IP so I'm not blocked too long.
