Arguably the most important day for IPv6 since it was created is World IPv6 Day, which falls on June 8th, 2010. This has been a highly publicized day when the top internet content providers like Google, Facebook, and Yahoo provide native IPv6 DNS records to their sites. But what does this mean? And how can you be prepared? Most of all, what will break, if anything? What will happen on World IPv6 Day?

I’m pleased to announce the first post in my blog’s new location, here at keepingitclassless.net. I have been running a casual blog from my house for the past two years with mixed success. Residential internet connections as they are, this was usually hit or miss regarding whether or not my blog was even reachable. I’ve moved all that content to a web host which should prove to be much more reliable.

Subnetting, in short, can be thought of as an adjustable “slide rule” that tells the network infrastructure the logical size of a sub-network, or subnet. This is useful if you know how many IP addresses you’ll to suit the needs of a predetermined number of PCs, so you can plan the size of your subnets to match that requirement. With IPv4, subnet masks are used to determine how big the subnets are.

That’s right, I’m taking the 640-802 exam from Cisco to attain my CCNA (Cisco Certified Network Associate) certification in one week!
The last four weeks have been quite eventful, although I’m ashamed I didn’t really start studying REALLY hard until about 3 weeks ago. Regardless, I’ve learned a lot! I’ve been following the book “31 Days Before Your CCNA Exam”, which is essentially a daily planner for study topics regarding CCNA material.

Often, especially in medium to large networks, it’s crucial to monitor the traffic traversing your networks.
Those in the networking industry know that tools like tcpdump and wireshark are crucial for deeply investigating network issues. Even developers use these tools to diagnose issues with applications utilizing network resources. Many times, it is helpful to install/use one of these tools to figure out exactly what’s traversing the network, by seeing the frames and packets themselves, in a visual way.

Setting up a new Android Development Environment in Eclipse? Having troubles? Maybe one of these two solutions will help:
PROBLEM #1 I recently re-imaged my PC and decided to build my Android Development Environment from scratch. Some recent modifications to my eclipse installation messed it up so I cut my losses and started over again.
This time around, I noticed that Eclipse Helios was available for download, and not only that, it was the first version of Eclipse to offer a 64-bit version of the IDE for windows.

I’ve been seeing a lot out on the internet about proxy servers and how to use them to circumvent your school or workplace internet filters.
Lifehacker recently posted an ~EIGHT PAGE~ walkthrough on how to set up such a proxy at home.
This is entirely too complicated. Not only is it a long walkthrough, but your traffic is still unencrypted. Unless your school, work or other bought their filter technology more than 4 years or so ago, they can still see the header of your packets and where they’re headed.
