2nd Irish IPv6 Summit: Dublin Castle19th May 2010
History of Event
• 1st Irish IPv6 Summit (Jan 2009)– h=p://www.ipv6.ie/summit2009
• Organised by Irish IPv6 Task Force– h=p://www.ipv6.ie/
• Supported by:– TSSG, HEAnet, DCENR, other members of the Task Force
• Sponsored by:– Science FoundaRon Ireland (SFI)
Context: Internet Governance Ecosystem
• ICANN -‐ in charge of names and numbers, sets policy• IANA -‐ operated by ICANN, follows policy• RIRs -‐ regional number allocaRon
– AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC
• Internet Society (ISOC) -‐ supports the ecosystem• Internet Engineering Task Force (IETF) -‐ defines thestandards (e.g. IPv4 and IPv6)– Internet Engineering Steering Group (IESG)– Internet Architecture Board (IAB)
Context: IPv4 Address Shortage
• IPv4 has over 4 billion addresses• But that simply is not enough
– Fewer that one for everyone on the planet– But we all use mulRple devices– And we’re creaRng new devices that talk to eachother rather than being used directly by a humans
– We’ve already used them all up, almost
Context: IPv4 Address Shortage
• We’ve put of the day as long as could– CIDR (sub divide address space more aggressively)– NAT (allow non-‐server devices to share public addresses)
• But now the Rme is running out• IANA /8 blocks are the basic unit of allocaRon toRegional Internet Registries
• PredicRons now indicate the last of these blocks willbe allocated in September 2011
Context: IPv6
• So there is no Rme for a long debate on thealternaRves
• The Internet community has already agreed on IPv6as the soluRon to IPv4 address shortage as aproblem
• IPv6 has about 340 trillion, trillion, trillion addresses• In actual use, addresses are structured for rouRngand as a result the number of addresses available iseffecRvely less
Talks Today Address
• End User– Home user must wait for ISP to provide IPv6, or run atunnel over IPv4
• Enterprise Networks (private and public sector)– Can make decision now to migrate to IPv6– Will have to deal with IPv6 in very near future anyway
• TelecommunicaRons operators and ISPs– Offer Internet connecRvity– Should be planning to migrate to IPv6 asap
What is the Internet?
• Explosive growth– The defining characterisRc of the Internet is its growth– This will stop, unless we migrate to IPv6– Arguably it has been one of the main drivers of the wholeeconomy, revoluRonising many business sectors
• Lowest barriers to service creaRon– The end-‐to-‐end architecture has allowed anyone on theInternet to offer a service to anyone else on the Internet
– NAT has broken this, IPv6 can help reintroduce it
