How to remove trailing zero

Can somebody help me how to remove the trailing zero from an ip address

$ip_add = "010.200.020.000";

The output should be "10.200.20.0";
I''ve been trying many regex techniques but still unsuccessful.
Thanks

It's probably possible to do this other ways, but oh well:

$ perl -le '$ip_add = "010.200.020.000"; $ip_add =~ s/0*([0-9]+)/$1/g; print
 $ip_add'
10.200.20.0
$

So the statement to use (as I'm approaching it) is:

$ip_add =~ s/0*([0-9]+)/$1/g;

$ perl -le'$_ = "010.200.020.000"; print; s/\b0+(?=\d)//g; print'
010.200.020.000
10.200.20.0
