Forged source address and routing address prefix hijacking have caused great threats since there are no source address validation mechanisms on the current Internet. Solving the address security problem and constructing a reliable Internet environment have become a critical issue. The foundation of a trustworthy Internet is the authenticated IP addresses. Therefore, researchers have proposed many solutions from different perspectives on these problems. This paper first introduces the notion of address and the current situation of address spoofing, then gives an analysis to the meaning of the address security. The paper analyzes and compares these security solutions in three dimensions: The architecture, the mechanism and the key technical means. Their performances are also summarized and evaluated. Finally, the study provides a proposal of constructing a general experimental platform for network addresses which enables different address schemes to be deployed and experimented.
