gethostbyname returns the proper IP address for valid domain names, fails for invalid domain names, but if I feed it a numeric invalidity like 1.1.1 or 9.9.9, it happily returns 1.1.0.1 or 9.9.0.9

Makes it kind of hard to check user input. What am I missing??

$name = "9.9.9";

@temp = gethostbyname($name);
unless (@temp) {
print "bad name\n";
exit;
}
$num = join(".",unpack("C4", @temp4));

print "num is $num for name $name\n";

Thanks for any assistance!

In reply to gethostbyname("1.1.1") returns 1.1.0.1 ???? by Anonymous Monk
