Private Subnetting One (PS1), an Algorithm for Private IPv4 Address Allocation

Network hosts in private enterprises require local connectivity without any external connections. These networks operated using TCP/IP protocol and require a private address space. This article proposes a novel algorithm for IPv4 address allocation for this type of networks. This algorithm can be used by educators of subnetting, ISPs, university students and researchers to simplify the process of IPv4 address allocation. A tool called Private Subnetting One (PS1) programmed under Java is introduced in this article. This tool can be used by network engineers or university tutors to explain complex subnetting problems to students in introductory networking courses, such as CCNA.
