IANA's announcement, in february 2011, that the last IPv4 blocks had been allocated to the Regional Internet Registries (RIRs) contributed to a significant increase in the interest for IPv6. (And to the "panic" around such a challenging migration.. )
Within networking and security circles, any mention to "v6" normally unchains a set of diametrically opposite thoughts:
- on one hand about the possibilities of services available to users
- ... and on the other hand about the amount of work (and time) it will take to achieve the migration to this new platform.
It is important to keep in mind that IPv6 differs from v4 in many areas that go beyond the (almost unlimited) addressing capabilities and the new header format. There are new processes that need to be understood so that you can successfully design and deploy a v6 network. For instance, paradigms such as performing Port Address Translation (address hiding) whenever your organization's machines connect to the Internet, need to be reconsidered...
In an attempt to give a basic contribution to your journey to v6, I decided to start a series of articles on my blog
(http://alexandremspmoraes.wordpress.com/), covering both connectivity and security aspects. Check it out and stay tuned for more...!
