+ | ======Synopsis:====== | ||
+ | $__iptoname__(<ip address>) \\ | ||
+ | $__nametoip__(<hostname>) | ||
+ | |||
+ | ======Technical:====== | ||
+ | These functions are used to convert an IP address to a hostname, and vice | ||
+ | versa. The $__iptoname__() function returns the hostname associated with | ||
+ | the given IP address, and $__nametoip__() does the opposite. | ||
+ | |||
+ | ======Practical:====== | ||
+ | These functions are used to convert between IP addresses and Internet | ||
+ | hostnames. Obvious reasons aside, they are mostly useful when you know | ||
+ | which of the two the input will be. They return nothing if the address | ||
+ | could not be converted, or if the input was invalid. The $[[convert]]() | ||
+ | function should be used if the input is known to vary. | ||
+ | |||
+ | ======Returns:====== | ||
+ | iptoname: hostname for the given IP address | ||
+ | nametoip: IP address for the given hostname | ||
+ | |||
+ | ======Examples:====== | ||
+ | <file> | ||
+ | $iptoname(127.0.0.1) probably returns "localhost" | ||
+ | $nametoip(localhost) probably returns "127.0.0.1" | ||
+ | $iptoname(localhost) error, input is not an IP address | ||
+ | $nametoip(127.0.0.1) error, input is not a hostname | ||
+ | </file> | ||
