Hurricane Electric’s Owen DeLong joins Ethan Banks and Greg Ferro to discuss TunnelBroker.net. What’s TunnelBroker.net? It’s a free service from Hurricane Electric that lets you connect to the IPv6 Internet across an IPv4-only connection. Want to get started with IPv6? This is a great way to go, not only for the connectivity, but also for the IPv6 education Hurricane Electric offers.
We keep the show pretty on-topic, and cover the following information.
- Who is Hurricane Electric?
- In simple terms, what’s the TunnelBroker.net service?
- Are these “real” routable IPv6 address blocks HE is issuing?
- Why is HE offering this service (a) at all and (b) for free?
- Who is eligible to use TunnelBroker.net?
- Why bother? Isn’t carrier grade NAT going to save us all?
- There are several types of IPv6 over IPv4 tunnels. What kind of tunnel is tunnelbroker.net using, and why was this type chosen over others?
- What sorts of devices can successfully bring up an IPv6 tunnel to HE?
- What sort of tunnel termination device is on the HE side? Is it redundant/resilient? In what way?
- Explain the tunnelbroker.net provisioning process. Is it automated or are there humans involved?
- Once the tunnel is up, what can you do with it?
- Can end users do anything crazy like advertise their own RIR-assigned IPv6 allocation to HE via BGP through the tunnel? Or nail up 2 tunnels to HE to have redundant virtual links for their IPv6 block?
- What happens if the user’s IPv4 tunnel endpoint is dynamically assigned, and the address changes?
- How does a person advertise their IPv6-enabled service with DNS?
- What resources would you recommend for a person trying to get smart about IPv6?
- What’s a good strategy for a business looking to do IPv6 multihoming?
- Is IPv6 prefix translation just a lame way for carriers to get out of upgrading their equipment?
