function _field_ipaddress_ip2long in IP address fields 7

Convert IP address in decimal form to long.

A wrapper around ip2long that ignores any leading zeros in each octet. Normally a leading zero will cause ip2long (and many other tools) to interpret the octet as an octal number. See for example http://support.microsoft.com/kb/115388
