Everyone on the planet is using IPv4 and the internet, yet the understanding ends at 'what is a LAN and what is a port' for a shocking portion of developers. Not knowing about federation[0] doesn't seem so bad.

i've even heard that some people use some kind of federated packet-switching network these days to communicate. it'll never catch on :)
