For the last few months, we have been working on setting up a dedicated room for my home office usage. This gives me the opportunity to plan for changes in the home network.
Key design ideas Cabling should support needs for now as well as the future but active hardware stays strictly for what I need for now. Hardware can be upgraded easily. It is not impossible to change cabling in the future since we have ducts - 0.
A nice short 20mins video by VOX on how the internet works. It covers the basic idea of connectivity a higher level and I am probably going to pass this link to friends & family members outside of the networking domain when they ask. It also covers 60 Hudson Street which I visited exactly an year ago. :)

I am in Noumea in New Caledonia in the Pacific Islands. Next week we have APNIC 46 conference and I would be moderating an exciting panel discussion with friends from Akamai, Cloudflare, Facebook and more about working of CDNs. If attending APNIC 46, please come & join this session.
If you are interested in connecting to Hurricane Electric (AS6939) in this region, please do drop me a message.

Often this comes into the subnetting discussion by my friends who are deploying IPv6 for the first time. How do you calculate subnets outside the 4-bit nibble boundary? This also happens to be one of starting points of APNIC IPv6 routing workshop where I occasionally instruct as community trainer.
So what is a Nibble boundary? In IPv6 context, it refers to 4 bit and any change in multiple of 4 bits is easy to calculate.
