Description

This module allows to make a reverse DNS (rDNS) lookup for incoming connection and provides simple access control of incoming hostname by allow/deny rules (similar to HttpAccessModule allow/deny directives; regular expressions are supported). Module works with the DNS server defined by the standard resolver directive. This module uses nginx core resolver cache when resolving DNS lookup, for a maximum of 30 seconds or DNS response TTL.
