A dot address (sometimes known as a dotted quad address) refers to the notation that expresses the four-byte (32-bit) IP address as a sequence of four decimal numbers separated by dots. Each number represents the binary value of one of four bytes. Look at this Internet address, for example: 205.245.172.72.
In 1974, after many failed attempts, a paper published by Vint Cerf and Bob Kahn, also known as âthe fathers of the Internet,â resulted in the protocol TCP (Transmission Control Protocol), which by 1978 would become TCP/IP (with the IP standing for Internet Protocol).
The Internet as we know it would not exist if if weren't for the efforts of a few specific individuals. J. C. R. Licklider invented the Internet in 1962 and managed its creation for years. Steve Crocker almost single-handedly created the Internet practice of open discussion and consensus-based protocols. Jon Postel and his small group at ISI were the central clearinghouse that kept everyone in touch with everyone.
