I noticed one of our clients was using an IP scheme for their internal network that wasn't one of the 3 groups of private IP addresses. They were using 200.200.200.0/24
They haven't had any problems so far, but will this cause any problems in the future?
Jump to PostIt would only cause issues if they need to get to and IP address within that range (i.e. 200.200.200.1 thru 200.200.200.254).
This IP address range is under LACNIC responsibility for further allocations to users in LACNIC region. Please see

I'm just going to ditto wldake's reply. Using a random public IP as an internal network doesn't cause any issues internally.
