This paper presents the basic design and principles of an FQDN-based Internet Architecture, where a host is identified in the Internet only by its FQDN (Fully Qualified Domain Name). The address shortage problem for the IPv4 paradigm has been marginally solved by introducing private addresses within the intranet and also by DHCP for public Internet access services. These two approaches have been independently developed. Considering more elaborate peer-to-peer communications such as voice over IP (VoIP) in the future Internet, the shortage of address space will become a serious problem for a call or session to be established. To alleviate this, this paper proposes an FQDN-based Internet architecture, assuming that a global endpoint identifier (EID) in the network is FQDN instead of an IP address. Since a countably infinite number of addresses can be logically produced by FQDN, this system resolves the address shortage problem assuming a caller uses the FQDN of the called terminal or host. This requires a dynamic address loading system from the FQDN of the called terminal into one of the available public IP addresses. After proposing a possible address loading system, some mathematical results on the required number of public addresses for VoIP traffic, the address space size of the derived Internet, etc. are also presented.
