TIL why YouTube buffers when my network is fine. Set network to prefer IPv4 or disable IPv6

learn.microsoft.com Configure IPv6 for advanced users - Windows Server

Provides step-by-step guidance for how to use the Windows registry to disable IPv6 or certain IPv6 components in Windows.

I have 2ms ping to YouTube and my network is wired 1gbit so it was odd to get so many buffering issues. So i did a search and this solution immediately solved the buffering issue! Prefer IPv4 or disable IPv6 and it's buttery smooth

I think this is specific to your network. The only time I’ve seen a difference between them it’s been the other way around, and IPv6 has been around for long enough that I think breakage related to IPv4 hackery will be more common than early-adopter IPv6 breakage.
Random question: You’re not on Verizon by any chance, are you?
- The default ipv6 issue was mostly when I try to play 8k HDR 60fps on youtube. 4k is BARELY fine (maybe very close when 4k HDR 60)
  
  Yes, I understand that you're having issues with IPv6. You're not on Verizon by any chance, are you?
  
  nope
  
  Not sure why you got down voted on this comment, but it would've been hilarious had you sidestepped his question again
  
  Hm, I only ask because I observed Verizon playing games with degrading Youtube service apparently on purpose in the past.
  shrug
  Glad you got it sorted out, in any case.
