Abstract

Reverse DNS (rDNS) is often used as a reliable data-source for
critical services, such as mail, security appliances or geolocation
services. Unlike forward DNS, rDNS remains understudied, especially from a deployment perspective. In this paper, we take steps
towards closing the gap, starting at regional Internet registries,
down to network operators in the lower hierarchy. To this end, we
use public and complementary data sources and find that around
40% of allocated IPv4 address space has well-configured rDNS entries. We highlight regional differences as rDNS deployment is
driven by mail and infrastructure providers in the developed world,
while national Internet registries and national ISPs are drivers in
the developing world. We study the use of classless delegation and
the prevalence of configuration errors breaking DNS resolution.
Finally, we observe that multi-regional organizations such as CDNs
and mail providers actively invest effort towards improving rDNS
deployment.
