Getting a new client changed over from SBS 2011 to a new 2016 Server. They are currently using 192.168.1.x for their internal scope - which I don't like. Have had issues with it in the past (with remote/VPN where user has same subnet at home).
Am I being overly cautious? Would be easier to leave subnet as is, but I think it is definitely worth the effort to change to something less 'common'. They have a mix of Windows and Macs with AFP connections, etc., so the change would require some work.
Looking for opinions with substantiation and/or 'been there / done that' reason why 192.168.1.x is OK or baaad.
