Change IP Search Depth for Moderating Registrations?

[HFB]

Can anyone point me to the code to edit to change the default IP depth to search for moderating new registrations? This is for a large forum using vB 3.7.0. The default depth of 2 is too server intensive. The depth can be selected in the Users Menu --> Search IP Addresses but there's no option to change it from moderate new registrations. Thanks.

I think it's in admincp/user.php, search for "depth=2".

Thanks, I found it.
