in reply to Representing a 32-bit integer

You want unpack, not pack, imo. Although, the document describing pack is a great deal more detailed. Also, see Socket for the inet_aton function, which is of great relevance here.

use Socket; print "", unpack("N", inet_aton("")), "\n";

UPDATE: This has been amusing me for many minutes now (e.g. unpack("N", inet_aton(""))). Thanks!
