Reaching the next billion
• Over 1 billion Internet users now- around 15% of all people
• Mobile phones are becoming Internet devices• Wireless cameras• The Internet of things• and so on and so forth.....
• IPv4 is limited to 4 billion addresses- roughly 3,5 billion usable

Getting it
19Tuesday, 30 June 2009
IPv6 Basics
• IPv6 address: 128 bits- 32 bits in IPv4
• Every subnet should be a /64• Customer assignments (sites) between:
- /64 (1 subnet)- /48 (65536 subnets)
• Minimum allocation size /32- 65536 /48’s
20Tuesday, 30 June 2009
Getting an IPv6 allocation
To qualify, an organisation must:- Be an LIR - Advertise the allocation as a single prefix- Have a plan for making assignments within two
years
Minimum allocation size /32
21Tuesday, 30 June 2009
Getting IPv6 PI address space
To qualify, an organisation must:- Not be an LIR - Demonstrate it will multihome- Meet the contractual requirements for provider
independent resources
Minimum assignment size /48

Doing it
26Tuesday, 30 June 2009
Change your face first•Web
•Authoritative DNS
•Mail servers
•Outsiders see these services
•Multiple mature implementations exist
27Tuesday, 30 June 2009
Don't•Seperate IPv6 features from IPv4
•Do everything in one go
•Appoint an IPv6 specialist
•do you have an IPv4 specialist?
•See IPv6 as a product
28Tuesday, 30 June 2009
Do•Phased approach
•Change requirements for new hardware
•Work outside-in, then inside-out
•Feature parity
•Dual stack
