IPv6 Default Allocation - What size allocation are you giving out

Thu Oct 9 04:07:09 UTC 2014

Like I said, this was my understanding.... I am glad that it is being pointed out to be in-correct.... 

I don't have a reason for why a /64 as much as I also don't have any reason Why NOT.... 

So, let me ask the question in a different manner... 
What is the wisdom / reasoning behind needing to give a /56 to a Residential customer (vs a /64). 

Regards.
