I wish my fiber ISP was part of that 50%. But nope, here I am behind a CGNAT and was promised IPv6 adoption about a year ago. Unfortunately the only other options in my area (downtown Milwaukee) are some form of wireless, DSL, or Spectrum.

Don't get me wrong, even though my speeds are only about 50% of spec (gigabit symmetric), the upload speed alone is a reason to avoid any other provider. I'm also paying about $25/m less than the equivalent download on Spectrum.
