With the exhaustion of IPv4, organizations will soon have to migrate to IPv6. While there isn't a hard deadline like with Y2K, the longer IT puts off IPv6 migration, the more difficult connecting to Internet and partner resources will become. IPv6 isn't rocket science, but there are a number of decisions that IT will have to make before and during the migration. In this tech center, we will dig into the architectural issues that IT will need to address from designing the IP layout through to migrating to supporting services like DHCP and DNS.

The Fear And Loathing Of /64s On Point-To-Point Links
October 04, 2011 08:28 AM
Posted by Jeff Doyle
I discussed in a previous article the necessity of abandoning IPv4 thinking when creating IPv6 address designs, and how our deeply ingrained need to conserve addresses can muddle our thinking. Nowhere does this conservative aversion to address waste snarl at us as menacingly as when we consider – completely compliant with the recommendations of ARIN and other RIRs – assigning /64 subnets to point-to-point links.

IPv6 Design: Forget The IPv4 Rules
September 06, 2011 09:00 AM
Posted by Jeff Doyle
You've acquired a nice new IPv6 address block, and now you need to come up with an IPv6 address allocation design for your network. If there is one bit of advice I can offer you as you begin your IPv6 address design, it's this: Abandon almost everything you've learned about IPv4 address design. Throw it right out the window.
