Only a couple of our transit providers, Tiscali and Verizon (f/k/a UUnet) will give us native/dual-stack transit. To help ensure independent connectivity we’ll have to turn up v6 peering at our various peering points. With IPv4 the driving […]

I don’t know where March and April went, but they’re long gone. Since we finally put in for a IPv6 allocation at work, I decided it was high time to finally get it working at home. It’s still a bit of voodoo but I finally have a few things working. My home network is on […]
