IPv6 Center of Excellence
Welcome to the Infoblox IPv6 CoE blog!
Paul, Tom and I share this blog, though we each publish under our own bylines. While we’ve usually got IPv6 topics on our minds, we’re also interested in hearing what’s on yours. If you have questions or suggestions, please feel free to get in touch with us at ipv6coe@infoblox.com.
Few things seem to cause as much confusion and anxiety among network architects newly tasked with IPv6 address planning as the current recommended practice of allocating a /48 per site.
After all, a /48 is 1.2E24 addresses. Or, to put it another way, 65536 /64 subnets (each containing 1.8E19 addresses). That works out to 281 trillion Internets for a single site!
Here's the fourth and final installment of my four-part blog on creating an IPv6 addressing plan.
Assigning Function and Location Significance to IPv6 Subnets
As mentioned, one major benefit resulting from the abundance of IPv6 addresses is the ability to assign function and location significance to groups of subnets derived from any larger allocation. While this technique works for any size allocation, we’ll continue our focus on the /48 allocation typical for one site.
