Configure Network Host-Only DHCP Server segments with Parallels 11 on Mac - parallels

Question

After upgrading from version Parallels 10 to Parallels 11, the company has removed the “Network Tab” from the preferences pane and changed my host-only network DHCP server segment to 10.32.x.x which broke all my exiting static host-only IP assignments. According to this post, configuring DHCP is now a “Pro” feature meaning we are expected to either pay more or update all my existing static IP assignments (to 20+ vms).
How can you update the DHCP server IP segment to match the pre-upgrade state?

As a manual workaround, you can modify the network.desktop.xml file which Parallels uses to assign network adapter segments. Credit for this workaround goes to Kevin01.
Shutdown/quit Parallels
Open the XML file with elevated permissions, in my case I have sublime configured in terminal, so I ran:
sudo sublime /Library/Preferences/Parallels/network.desktop.xml
Modify the adapter settings located under "Host-Only". In this example I’ve set my network segment to 10.211.55.x
