How DNS Misnaming Distorts Internet Topology Mapping
Overview Network researchers commonly use reverse DNS lookups of router names to provide geographic or topological information that would otherwise be difficult to obtain. By systematically examining a large ISP, the paper finds that some of these names are incorrect. This paper develops techniques to automatically identify these misnamings, and determine the actual locations, which it validates against the configuration of the ISP's routers. While the actual number of misnamings is small, these errors induce a large number of false links in the inferred connectivity graph. The paper also measures the effects on path inflation, and finds that the misnamings make path inflation and routing problems appear much worse than they actually are.
