APM/TCL question, how to replace the fouth octet in network address which include subnet

I have a variable which I inquiry from AD, the variable is in form of x.x.x.x/255.255.255.0 - I need to replace the fourth octet with "0", normally it is set to .254 I have tried this but it does not...

I haven't messed with expressions too much in APM, so I'm not sure if string map is supported in them, but if it is, string map should work:

% set x 10.10.10.254/255.255.255.0
10.10.10.254/255.255.255.0
% string map ".254 .0" $x
10.10.10.0/255.255.255.0

keep in mind this will match any occurrence of .254, so if there is a chance it will show in the 2nd or 3rd octet you'll need to interrogate a little deeper.
