Contemporary map of the entire Internet in semi-production phase (many hosts attached to the ARPANET were still using NCP at this point) in February 1982. The ovals are sites/networks (some sites included more than one physical network), the rectangles are individual routers. No individual hosts are shown. Drawn by Jon Postel of the Information Sciences Institute, under a DARPA research contract as part of Internet development.
