IPv4The purpose of this document is to present a proposed Internet Protocol Version 4 (IPv4) implementation, also known as TCP/IP (Transmission Control Protocol/Internet Protocol) framework as our primary means of communication within our network infrastructure. We are currently using an existing mainframe system that limits current means of network connectivity with other evolving network systems and it is in our best interest to look to the future and keep up with the changing times as IT technicians. information. I will provide a detailed analysis of the brief history of TCP/IP, understanding IPv4 addresses, subnetting, configuration, and the benefits of using the TCP/IP framework. This will significantly increase the overall success rate of our business. AnalysisOur current network infrastructure uses an existing mainframe system and our collective knowledge as a team is limited to this network suite only. This is devastating to our organization’s productivity and overall communication. It is imperative to expand our horizons, learn and implement new technologies. This will collectively increase our knowledge of information technology as a whole. Additionally, this will allow us to be competitive with many other organizations using newer computer systems that are currently using the latest version of Internet Protocol. Proposed Solution The latest version of Internet Protocol that we should implement is IPv4, also known as TCP. Structure/IP. This is why IPv4 is called TCP/IP for the first two main protocols, among its suite of protocols, which were developed by the United States Defense Advanced Research Project Agency, also known as DARPA, in the 1970s (Kozierok, 2005). ...... middle of article ...... adapt to current technologies.
