What’s the main difference between IP version 4 and IP version 6? or Can someone explain the key diff

Fun fact: IPv6 doesn’t need broadcast. It’s all multicast or unicast. Less network clutter!

But the transition? Ugh. Dual-stack is the way (run both IPv4 and IPv6). Check your OS support with `ipconfig /all` (Windows) or `ifconfig` (Linux).

For a deep dive, [IPv6.com](http://www.ipv6.com/) has solid docs.
