1. Yes, you still use tunnelbroker.net if you wish you your own IPv6 PI
space tunneled. HE does require you to have an ASN as well. With this
you can multihome up to 5 of their PoPs.
Find more info at their site:
However, they will give you up to 5 tunnels, each with a /64 and
optional /48 allocated from their address space. However as this is
allocated from their address space, you cannot multihome with it.
They also do have a premium service you can purchase for IPv6 transit as
Also they will sell you native IPv6 with IPv4 service as well. You
provide the circuit to them.
2. If you have transit only with HE, all IPv6-connected Internet users
can access you with the except of those single-homed to Cogent or Level
3. Both Cogent and Level 3 refuse to route any IPv6 traffic destined to HE.
Having said that, Hurricane Electric has the most IPv6 peers at present
(more than 3 times the amount of Cogent and Level 3):
I'm using HE for multihomed transit using my PI /44 and ASN (AS19621).
I'm waiting while AT&T and Verizon try to upgrade their PoPs (AT&T in
San Jose, Verizon in Sacramento) to provide me transit on my existing
enterprise IPv4 circuits. I'll continue to use HE as backup transit
even once I get IPv6 connectivity to either or both of the telcos.
The nice thing is that you can get your feet wet with HE for free and no
commitment and get started now while the giants still sleep. Plus, who
knows, HE may remain an IPv6 giant as others grow up, and perhaps this
will raise their IPv4 status to that of coveted Tier 1. Maybe IPv4
transmit won't matter in 10 years, and they'll just stay the top IPv6 dog.
