You may have run in to this, but Hulu also limits (or they were before I
canceled the service personally) the number of “homes” you can use it at,
and they tracked this by IP. So, if your customer’s IP changes more than a
few times a year they will not be able to use the service they’re paying
for.

Last time I was responsible for said problem I was looking at alternate
solutions to do CGNAT on, and reducing the domains from an architecture
perspective…obviously they both have big repercussions.

I'm not so sure about that.  Our customers are all offered dual-stack
(DHCPv6, DHCPv6-PD).  Do any of the common streaming services support
v6 yet?  Last I checked, Hulu did not.

I just checked and it looks like Youtube and Netflix do which is a
pretty good chunk. Not sure about Amazon Prime. I was actually thinking
about social media which i think it's pretty well supported.

Hi Jon,

So is this easier than what the mobile carriers are doing -- 464xlat,
isn't it? Probably a sizeable portion of the traffic would be running
native v6, right? Obviously it wouldn't run into these sorts of
problems.

 We started rolling out CGNAT about 6 months ago.  It was smooth

 for the first few months, but we eventually did run into a number of
 issues.
