RIPEn at Home – Surveying Internal Domain Names using RIPE Atlas

Poster and extended abstract presented at the IFIP Network Traffic Measurement and Analysis (TMA) Conference, May .

Internal domain names are domain names that are resolved locally and not by the global DNS. Name collisions occur if an internal name is resolved in the global DNS, e.g. if queries are accidentally sent to a public resolver. This can lead to security issues. While previous studies of name collisions used passive measurement data, we use active measurements on RIPE Atlas to survey the use of internal names in home networks. We discover 3092 names, used by 4305 probes, of which 34.51% are at risk of collision if their top-level domain is delegated.
