The Dynamic Host Configuration Protocol (DHCP to its friends) is the magic by which your laptop knows how to get to Twitter on a brand new network about which it knows nothing. DHCP can tell your computer what its address should be, and where it should go to connect out to other networks. It can also tell your laptop weird stuff, like that it should run all the traffic through a proxy you’ve never heard of!! IT ALSO WORKS MOSTLY BY YELLING!
