RIPE NCC ASN32 Assignments
Competitive disadvantage?
Alex Le Heux, RIPE62, 2011-05-05
Last /8 implementation
• Last /8 implementation:– Address space returned to the RIPE NCC after the last /8 policy comes into effect will be treated the same way as the last /8.

“Upgrade” of /32 allocations
• First IPv6 allocation on file: August 12, 1999
• Detailed deployment plans were rare in those days
• Years later, some holders of /32s realise they actually have a few million customers
• Solution: Return the /32 & re-evaluate

IPv6 PISore points and background information
Alex Le Heux, RIPE62, 2011-05-05
IPv6 PI, Part III
• Report on Registration Services’ experience with the current policy
• Provide some background information and numbers relevant to the current IPv6 PI discussion
10
Alex Le Heux, RIPE62, 2011-05-05
IPv6 PI, Part III
• Current IPv4 PI policy:– “PI space cannot be re-assigned or further assigned to other parties.”
– “IP addresses used solely for the connection of an End User to a service provider [...] are considered part of the service provider's infrastructure.”
11
Alex Le Heux, RIPE62, 2011-05-05
IPv6 PI, Part III
• Current IPv6 policy:– “Assignments [...] are not to be sub-assigned to other parties.”
12
Alex Le Heux, RIPE62, 2011-05-05
IPv6 PI, Part III
• No DSL
• No Cable
• VPN
• No co-location
• No virtual servers
• No SSL hosting
• No buts and no exceptions
13
Alex Le Heux, RIPE62, 2011-05-05
IPv6 PI, Part III
• Sore points:– Thousands of current IPv4 PI space holders see no way to deploy IPv6
– Hard to explain why we can assign IPv4 but not IPv6
– Blurred distinction between ISP and end-user

• In the past, when ISPs were real ISPs and end-users were real end-users...
• The world was probably a simpler place

• Application Service Provider– Writes software for clients
– Then hosts the application as well
– Sets up a completely independent infrastructure for each client
– End-site? ISP?

• The sharp distinction between end-user and ISP is gone
• “Old-school” end-users still exist, of course
• But more and more complex services are built on top of other complex services built on top of...
22
Alex Le Heux, RIPE62, 2011-05-05
IPv6 PI, Part III
• The complexity of deciding if something is an ISP or an end-user has increased
• If it even makes sense to make the distinction at all, in some cases
• This is hard to do in a fair and consistent manner

IPv6 PI, Part III
• Look at the IPv4 routing table to see what might happen with IPv6
– RIR delegated stats files
– Anything assigned or allocated before 1996 considered “legacy”
– RIS
– A prefix considered “in the DFZ” if seen by at least 10 RIS peers
