IPv6 Shorthand Notation Explained
Published by Doug Bassett | April 5, 2013Video Runtime: 2 minutes
Video Summary:
IPv6 uses hexadecimal for addressing. Since IPv6 addresses are 128 bits long, this can make for a lot to type. In this video, Doug Bassett explains the shorthand notation for IPv6.
This is an example of the real-world, online HD certification training done at StormWind.com.

CCNA (ICND2) Mentor Question of the Day
Published by Anthony Sequeira | July 16, 2012Which of the following IP addresses fall into the CIDR block of 115.64.4.0/22? (Choose three.)
A. 115.64.8.32
B. 115.64.7.64
C. 115.64.6.255
D. 115.64.3.255
E. 115.64.5.128
F. 115.64.12.128
We know that this subnet mask of 22 falls into the third octet. Converting the third octet of the IP address and the third octet of the subnet mask, we have to the following:
StormWindLive Cisco Mentor Question Spotlight - NAT versus PAT
Published by Anthony Sequeira | March 28, 2012Hi Anthony,
My understanding of nat is that it keeps a table as to what host is requesting information from outside the subnet.
It then changes the private ip to a public ip and sends the packet on.
When it receives the return it looks up in its table who it is for and then routes it to the correct inside host.
My question is what is the difference between nat and nat overload.
I just rewatched lesson 8 part 2 but I'm still confused, and the book isn't making any clearer.
Do you know of any other place to get a good explanation.
Thanks

Super Speed Subnetting-The Conversion Table
Published by Anthony Sequeira | March 27, 2011This post discusses the use of a subnetting conversion chart in the ICND1 and ICND2 exams. We all know that we need to learn TCP/IP Subnetting for success in the ICND1 and ICND2 exams. In fact, we must completely master it and understand how and why it works the way it does, and then we have to learn tricks and strategies to ensure that we can succeed in the exams given the intense number of questions we will face and their complexity. Note that it is very important that you master subnetting first as a subject, and then you can go on and learn the shortcuts for solving the questions.
