I'd like to do some IPv6 testing at home, using VirtualBox. I could create a few VMs and leave it at that, but I feel that to really test IPv6 you have to scale up to many nodes.
So I wonder: what's the smallest distribution of Linux or BSD that I could use for this? I only need IPv6 support, a shell and a few net utilities (ping, telnet, nslookup/dig, and little more).
My aim is to create many small VMs, ideally with RAM-backed storage (I've got 12GB of RAM, and using multiattach images I should be able to store them in tmpfs for quicker access) and little RAM (<=64MB). Then I'd unleash them against some radvd and/or dhcp6 server to test IPv6 stuff.
