What is IPV6?

• IPv6 fixes a number of problems in IPv4, such as
  the limited number of available IPv4 addresses.
  It also adds many improvements to IPv4 in areas
  such as routing and network auto-configuration.
  IPv6 is expected to gradually replace IPv4, with
  the two coexisting for a number of years during a
  transition period. -http//www.ipv6.org/

Advantages

• Restoration of the end-to-end Internet model
• Larger number of addresses
• New Node Discovery Architecture
• Stateless Autoconfiguration
• Enhancements to Mobile IPv6 routing

Addressing

• IPV6 addresses are normally written as eight
  groups of four hexadecimal digits
• 20010db885a308d313198a2e03707334
• If one or more four-digit groups is 0000, the
  zeros may be omitted and replaced with two
  colons().
• For example 20010db80000000000000000142857
  ab can be shortened to 20010db8142857ab.

Deployment

• US Government Sectors will be running IPV6 by
  summer 2008
• The One Laptop per Child program will use IPV6
  (several million hosts very quickly)
• Others as needed IPV6 will coincide for IPV4 for
  a few years forecasts suggest IPV4 address
  space will be exhausted by 2011.

Challenges

• LeMaster alleged that at this point there is no
  clear guidance as to how a federal agency should
  implement IPv6 and ensure that it is secure. -

• Since there is very little ROI, getting
  organizations to switch is the hardest part
