net_ip2host

The net_ip2host function transforms a textual IP address into a fully qualified domain name and returns that name.

This function works only if the DNS directive is enabled in the obj.conf file. For more information, see Oracle iPlanet Web Proxy Server 4.0.14 Configuration File Reference.

Syntax

char *net_ip2host(char *ip, int verify);

Returns

A new string containing the fully qualified domain name if the transformation was accomplished, or NULL if the transformation was not accomplished.

Parameters

char *ip is the IP address as a character string in dotted-decimal notation: nnn.nnn.nnn.nnn

int verify, if nonzero, specifies that the function should verify the fully qualified domain name. This parameter requires an extra query but you should use it when checking access control.
