Name
HostNameLookups
Synopsis
HostNameLookups on|off|double
Description
[server config, within <VirtualHost> or <Directory>]
Enables whether the server should perform hostname lookups on clients
instead of simply recording the IP address in the connection logs.
If the double option is specified, the server performs
a forward and reverse DNS lookup; this ensures that the client hostname
maps to its IP, as well as the IP mapping to the DNS name. The
double option is available only in Apache 1.3. The default
with Apache 1.2 and below is on, while the default with
Apache 1.3 is off.
(All; double option in Apache 1.3 or above)
