Re: 2^128 Addresses Claim is inaccurate/misleading Sorry for being pendant but it is important that we use the same terminology to keep this clear. Your intent is correct but you terminology isn't.
said by AVonGauss:... For residential customers, I doubt you will see anything larger than a /64 given and its entirely possible that a smaller allocation would be provided - although I hope thats not the direction it takes. I think you have the words smaller and larger confused. I think, for IPV6, it's best to stay away from using the term subnet mask, instead use prefix legth. A /48 prefix length is smaller (more hosts and fewer networks) than a /64 and you will never see an ISP end user (us, consumer grade customers) with a /48. The /64 prefix length is larger (more networks, fewer hosts) and is a possible end user prefix length as it follows the ARIN recommendations.
It is quite possible that the end user could see an even larger prefix length such as a /96 (32 bits for the end user) but this would be out of step with the ARIN recommendations. It is possible and it's legal to do.
The issue here is for the network engineers. They have to balance the size of their route tables (router memory usage), the needs of the end user and the standards the end user consumer equipment is likely to follow. As a Comcast customer (and a network engineer) I'm looking forward to what Comcast comes up with. It may very likely set precedences for other ISPs to follow.
Edited for spelling and clarity.

Monroe Township, NJ | I understand, it was also why I suggested it (so others might follow suite). It took me almost a month to stop saying sub-netmask and get the order of smaller/larger straight. Also I reread RARPSL's post and found it very confusing. I couldn't quite figure out what he was talking about with the IPv4/IPv6 /xx portions of his post. Mixing the terminology makes for a messy conversation. IPv6 is going to be confusing for a while until it become the most used protocol.
