7 Actions to get your network ready for IPv6

IPv4 is depleting so fast and time comes to get ready for IPv6. IPv6 may come to real life by 2012/2013.

I am not going to explain them in this post, they are explained everywhere over the internet. However, in short well-known attributes must be recognized by all BGP implementations, some of them are mandatory and must be included in all update messages, others are discretionary and may …

Try yourself Now: What is your definition of SUCCESS and do you consider yourself successful?.
