BIVBlog #11: More on the business case of IPv6

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.

IANA (Internet Assigned Numbers Authority
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).
