Lightweight Ubuntu for networking purposes
What is best lightweight Ubuntu only for networking purposes?
I'm doing a project related to networking based on IPv6 and I want to test it.
So I need to create a IPv6 Virtual Network in my Linux OS (I use Ubuntu). Also I need to create some virtual hosts in my virtual network and setup static ips (local ips) for each and every host. And I need to run a terminal on each virtual host.
I figured running several instances of a VM is the only way to establish a network. Lots of mini-distributions are there, but I couldn't find a good one for my project. Networking configurations should be there.
