While administration may be necessary in today's large complex IP networks, it is unacceptable for emerging networks such as home networks, small office home office (SOHO) networks, ad-hoc networks, and many others. These networks require zero manual administration and configuration. Zero-configuration (Zeroconf) networks are a particular class of IP networks that do not require any user administration for correct operation. The first step in auto-configuration of zeroconf networks is IP address auto-configuration. While there are proposals for IPv4 host auto-configuration, a general solution for IPv4 auto-configuration of multi-router zeroconf networks does not exist. This paper reviews IPv4 host and single-router auto-configuration algorithms and extends them to more complex multi-router zeroconf network topologies. To the best of our knowledge, we are the first to propose a solution to IPv4 auto-configuration of multi-router zeroconf networks. © Springer-Verlag Berlin Heidelberg 2005.
