What is an IP address?
• Internet infrastructure address– Globally unique*
• A finite common resource– IPv4: 32-bit number
• e.g. 192.131.13.3• 4 billion addresses available
– IPv6: 128-bit number• e.g. 3ffe:1a00:ff00::• Potentially*, equal to (IPv4)4
• IP does not mean “Intellectual Property”

IPv4 vs IPv6
IPv4: 32 bits
• 232 addresses = 4,294,967,296 addresses = 4 billion addresses
IPv6: 128 bits
• 2128 addresses? = 340,282,366,920,938,463,463,374,607,431,770,000,000 = 340 billion billion billion billion addresses?
• No, due to IPv6 address structure…

128 bits
How much IPv6?
Topological Interface/0 /64 /128
Infrastructure Site/0 /64/48
• 248 site addresses = 281,474,976,710,656 = 281 thousand billion site addresses
• 264 “subnet” addresses = 18,446,744,073,709,551,616 = 18 billion billion subnet addresses

How are IP Addresses managed?
and how did we get here?
24 March 2003 RIR Meeting with the ICANN GAC Rio de Janeiro
1981 - 1992
1981: RFC 790
1987: RFC 1020
1992: RFC 1366
RFC 12611991
“The assignment of numbers is also handled by Jon.If you are developing a protocol or application thatwill require the use of a link, socket, port, protocol,or network number please contact Jon to receivea number assignment.”

What are RIRs?
• Representative of ISPs globally– Industry self-regulatory structures– Non-profit, open membership bodies
• First established in early 1990’s– In response to call from IETF (RFC1366)– To satisfy emerging technical/admin needs– Voluntarily by consensus of community
• In the “Internet Tradition”– Consensus-based, open and transparent
18
What do RIRs do?
• Internet resource management– Primarily, IP addresses – IPv4 and IPv6– Registration services (“whois”)
• Policy development and coordination– Open Policy Meetings and processes
• Training, outreach and liaison– Training courses, seminars, conferences…– Liaison: IETF, ICANN, ITU, APT, PITA, APEC…– Newsletters, reports, web sites…
• Projects– Various operational services and support
• RIR collaboration– Represented by the NRO

IPv6 – Summary
• The good news…– IPv6 is available– IPv6 addresses are very easy to get
• The bad news…– Complexity: significant cost and learning curve– Demand? Do users want it?– “Chicken and Egg” syndrome
• The reality: A long, hard, transition– “Changing engines mid-flight”– Long process – 10+ years to complete– Critical message: Start now!
