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).
Bob Kahn and Vint Cerf invented the Transmission Control Protocol (TCP) which moves data on the modern Internet, in 1972 and 1973. If any two people invented the Internet, it was Kahn and Cerf-but they have publicily stated that no one person or group of people invented the Internet.
