And just for completeness, script above can be simplified to

return InetAddress("192.168.56.0", 24).contains($node.ipAddress);

First of all two first lines should end with ; char.
There is no isInSubnet() method on InetAddress class, but there is contains() method on subnet, so we should go opposite way and check it on the subnet, there's an example here: https://netxms.org/documentation/nxsl-latest/#_instance_methods_18
So, modifying your code:

subnetObject = InetAddress("192.168.56.0", 24);

if (subnetObject.contains($node.ipAddress)) {
    return 1;  // match
} else {
    return 0;  // no match
}

$subnet = InetAddress("x.y.z.0")
$mask = 24

if ($node.ipAddress.isInSubnet($subnet, $mask)) {
return 1; // match
} else {
return 0; // no match
}

I got this, but it’s not working. Can you please modify it?

$node.ipAddr (string)

or $node.ipAddress (instance of InetAddress): https://netxms.org/documentation/nxsl-latest/#class-inetaddress
