I have a suspicion that these folks acquired IP space that was previously marked as part of a VPN provider, or Hulu is detecting it wrongly as VPN provider IP space.

If you look at some of the blocks I’ve seen, they have some interesting history/registration that seems to appear that way.  I’ve pointed folks at Hulu at this thread and an encouraging them to follow-up.

If you acquired IP space from a broker, you should follow up with them about the geolocation issues, and you should know what it was used for in the past.

If you are using a CDN to serve content, make sure you can serve over v6 and can also do geolocation over IPv6.  Finding the IP space used to geolocate generally isn’t difficult.  I had previously found some of these myself.

It’s also that Hulu is owned by content owners that can decide to be strict about their content rights.  I’m not a fan of geoblocking and vote with my wallet to not give Hulu money.  While I understand your customers may, the lack of a fix is also a market signal.
