In the previous episode I’ve claimed that there is a business case for IPv6. But since you are hopefully paranoid enough not to believe every claim someone makes on YouTube, here are the details and the rationale.

- The organization that allocates IP addresses to the RIRs.
- RIR (Regional Internet Registry)
- The five organizations that allocate IP addresses to Internet Service Providers (ISPs) and large enterprises in their respective regions: AfriNIC (Africa), APNIC (Asia/Pacific), ARIN (North America), LACNIC (Latin America) and RIPE (Europe/Middle East)
- APNIC (Asia Pacific Network Information Centre)
- This was the first RIR to run out of IPv4 addresses.
- RIPE (Reseaux IP Europeen)
- The second RIR running out of addresses.
- Geoff Huston’s IPv6 presentation at RIPE 67
- This is the presentation that I’ve got most of the data I’ve mentioned from; Geoff frequently gives updates on this presentation and this is the latest one I know of.
- CGN (Carrier Grade NAT)
- A last ditch effort to make even more people use the fixed number of IPv4 addresses available.
- DS-Lite (Dual Stack Lite)
- A companion technology to CGN transporting IPv4 packets over IPv6 between end users’ home routers and a matching gateway (called an AFTR, or address family translating router).
