Hulu / ESPN: Commercial IP Address

Hello, I have a customer that is using Hulu Live to stream ESPN, however it isn't showing up in their Channel list.  They reached out to Hulu and it's because their IP address is 'commercial'.  We have many customers using Hulu without problems, but it seems specific to ESPN.  Anyone else have this issue?  Do you reach out to ESPN or Hulu? If anyone has any information, please share it.  Appreciate your help in advance! Best Regards, Jason Canady Unlimited Net, LLC Responsive, Reliable, Secure
