Which are expensive, especially for an Indian Reservation, not the deep pockets of some MSP.&lt;p&gt;The users are behind CG-NAT.&lt;p&gt;But instead of using IPv6 which is cheaper (no need to maintain CG-NAT, translation devices, or deal with traffic that is being routed way more expensively) the Roku devices are only streaming over IPv4.&lt;p&gt;Each new user that adds an IPv4 only device adds additional load the CG-NAT and additional capacity will need to be provisioned. That is an additional expense and burden.&lt;p&gt;Most of my traffic at my house (on Comcast) is over IPv6, because most if not all streaming services now support IPv6 for content delivery, so the small amount of data that may need to go over IPv4 when the majority can go over IPv6 reduces the load on IPv4.</text><parent_chain><item><author>hitpointdrew</author><text>Who the hell is giving their Roku a public IP?
