8. • IPv6 is designed as a direct replacement for IPv4
Provides familiar best-effort datagram delivery
IPv6 address has a prefix to identify the destination subnet and a suffix to
identify the host interface
Not backward compatible with IPv4; carried in parallel as a multi-protocol
network
• 128-bit addresses solve address exhaustion problem
Prefix/suffix boundary effectively fixed at 64 bits
Fixed prefix makes address architecture a prefix assignment problem rather
than a subnet size problem
64 bit identifier allows hosts to self-assign addresses, in addition to DHCP
• Home networks will use global IPv6 addresses
Restores full connectivity to devices in the home
Utilizes extensions to DHCPv6 for prefix assignment automation

9. Dual Stack Tunneling Translation
(NAT)
• Typically easiest to • Encapsulate v6 traffic • Allows multiple local
implement in v4 packets (and addresses to share
vice versa) single IP address
• Built into many
modern operating • Can reduce efficiency • Not true end-to-end
systems connectivity
• Routing can be
• Implements v4 and v6 sub-optimal • Can create
independently, as well complications and
as in hybrid form disruptions
“Dual stack when …tunnel where you …translate when you
you can… need to… must.”

approach with careful validation 2. Assess those areas to determine the scope of your IPv6
and testing to avoid disrupting design.
the IPv4 network or introducing
vulnerabilities. 3. Develop a design that enables IPv6 to be introduced
without disrupting your IPv4 network.
4. Test and implement IPv6 in pilot mode, then extend over
time into production deployment.
5. Repeat steps for subsequent areas of your network
through ongoing optimization.
