Introducing IPv6 | IPv6 Headers
The beauty of the IPv6 header is that it has been streamlined and contains only those pieces of information that are necessary on every IPv6 packet. All optional IP information is encoded in extension headers, which are added to packets between the standard IPv6 header and the upper-layer header.
IPv6 Transit and Peering
We (the Global Network Engineering Community(GNEC)) have made many mistakes with IPv4 Peering and Transit configurations and operational practices. As operators begin turning up more and more IPv6 E-BGP sessions with peers and transit providers, there is an opportunity to do things right from the beginning.
Introducing IPv6 | Classifying IPv6 Addresses
As with IPv4, an IPv6 address serves as an identifier for an interface or group of interfaces. Also like IPv4, IPv6 addresses come in several types, based on how they represent those interfaces. IPv6 has three types of addresses. This post covers all three, plus some special purpose addresses as well.

Introducing IPv6 | Understanding IPv6 Addresses
The primary difference between IPv4 and IPv6 addresses is length. IPv4 addresses are 32 bits long and IPv6 addresses are 128 bits long. This means that an IPv4 address is made up of 32 1s and 0s while an IPv6 address is made up of 128 of them – 128 binary digits. This massive length forces IPv6 addresses to be written using a different notation than IPv4 addresses and thus makes them very easy to distinguish from IPv4 addresses.

Reckoning 2011 and Resolving for 2012
2011 was a fascinating year for me: I changed jobs, got divorced and fell in love (twice). I moved from the suburbs to the city and started riding to work. I was interviewed by Juniper, took 16 trips to 13 different cities, joined TheHundred Denver, and was kicked out of Canada. I started speaking more, working less, and spending more time with my kids. I published my second book, co-authored my first Internet-Draft, filed my first patent application, and re-discovered my spirituality. Oh, and I turned 30...
