The implicit "design plan" or "construction plan" of the Internet is manifested in rules of interaction, value patterns, styles of communication and in the technique of those who set up this network. The developers and users of the Internet were more or less left to their own devices for twenty years of development and built and developed the Net step by step, following shared ideas, common interests and basic design principles such as "keep it simple," but without a strict "great plan". In the seventies and eighties, no one could probably have even imagined what the Internet would later become, which services and applications it would have to offer, how high its number of users would rise: One example for this is the numerical limitation of IP addresses and domain names (especially .com domains). This poses all number of problems for the organizations that hand out addresses. When IP addresses were defined, the exponential rise in IP domains was unforseeable.
