IPv6 allocations

I was wondering if Sonic had looked into providing larger IPv6 allocations to customers? While I realize that even the granted /60 represents more addresses than anyone could possibly need, the problem is that some IPv4-v6 transition technologies (such as stateless client auto-configuration) depend upon a /64 allocation. With that being said, it limits the amount of networks that a /60 can be split up into. Like many other users configuring IPv6 on their local nets, I have set mine up for some testing which has made multiple networks a necessity.

Hurricane Electric is said to grant users who have activated their free tunnel a /48 (from a /64) after a short amount of time. I was hoping to get a larger allocation from my provider of choice prior to going to someone else.** Is this possible?


Thanks in advance,

Extremely Satisfied, SONIC.NET


** My intention is not to bad-mouth Hurricane Electric, but rather to point out that some organizations are giving away IP allocations that are not currently available from SONIC.NET.

Isn't a /60 larger than a /64?

10. IETF expects that you will assign a /64 for point-to-point links

Fewer typos because all subnets are the same size
You can use longer prefixes but what's the point?
/126 will break Mobile IPv6 Home Agent discovery
/112 leaves final 16 bits free for Node IDs
Use /64 unless you have read and understand RFC 3627 http://tools.ietf.org/html/rfc3627
