Today, I learned new math words like Septillion +24 zeros and Quintillion +18 zeros. I have been checking out the IPv6 CIDR Table written by Rick Hodger and TDOI NETWORK

Enjoy!

IPv6 Tiger Team virtual helpdesk


"Mmm. Yes! Mmm. Yes! Let go. When you have understanding, your fate the Force will guide. Of your emotions be mindful, but do not forget the passivity of the moment. My ally is the Force, and a strong ally it is." 

Hmm.. Well in the mean time, I want to understand and check out the IPv6 Tiger team they have a summary  of the key results of the 6NET project, offer pointers to appropriate tutorial material, and to offer access to IPv6 expertise, via our virtual helpdesk.

Enjoy!
