Cool thing, which I missed when flying to Mexico last time… Internet on the plane. Using pretty funky networking techniques, and it’s fun to see how the data available on the internet (I could check it from my own BGP routers as well) can be used to see where planes are (not very accurate but still). Just a pity they had to waste a whole /24 per plane, and then not even use the IP addresses but NAT everyone… The registered block is a /16, so that’s enough for 256 planes; there may be more blocks, I didn’t check.
