My bet is the IP range in your office is the same as on the control subnet of the processors, IIRC that's by default 172.22.0.0/24.

 

 

You can change the IP range on the processors through toolbox in the ethernet settings or with the text console command csrouterprefix. If you're using the control subnet you may want to power cycle the devices on there for them to grab an IP in the new range, if you have addressed some with static addresses you also need to change that to the new IP range manually.
