Designing a hierarchical DHCP server´s model to automatically provide dedicated IP address anywhere in the world with mobility

A new organization of Dynamic Host Configuration Protocol (DHCP) server´s is proposed in this research paper. This hierarchical model is designed to provide each user with a dedicated IP address with an option to move anywhere in the world. This design makes a user´s IP address independent of an ISP (Internet Service Provider). Dynamic Host Configuration Protocol servers are organized into three levels i) Organization level DHCP server ii) Country level DHCP server iii) Root level DHCP server. One IP address is bind against each registered user and this information is stored at all root level servers. A user can now access internet through any ISP, ISP will use the hierarchical design to search for users dedicated IP and a user will always be facilitated by his dedicated IP address. A small protocol is also designed to provide effective communication between different level DHCP servers, between ISP and DHCP server and between client and ISP. This design does not demand any complex changes in existing system rather some intelligent organization of already existing DHCP servers is sufficient to create the new model.
