CGNATs and IPv6 over Mobile Broadband
In this lab, we will explore the default behaviour of Mobile broadband with an emphasis on addressing. Before we start looking at the addressing or performance of these networks, lets start with a baseline. Start with the Ubuntu Virtual Machine in the labs.
Wired LAN
Open a terminal an type:
ip a
What is your IP address? Is it IPv4, IPv6? Is it private/public?
Run a speed test at:
https://www.speedtest.net/
What is your upload and download speed? What latency is reported.
Try pinging:
8.8.8.8
This is google DNS server. Only ping for a couple of seconds to prevent the university being blacklisted. What latency do you get?
