VMware Workstation includes a network utility that allows you to manage the virtual networks. Typically virtual machines will use NAT (Network Address Translation) to automatically assign a virtual IP address that hides behind your host address, but the default range of 192.168.200.0/24 may not work for everybody.
You can change this address range to anything you like easily. Note that you should not have virtual machines running during this.
First open the Manage Virtual Networks start menu item:
Click the Host Virtual Network Mapping tab, and then click the arrow button next to the VMnet8 dropdown box. VMnet8 is the default NAT adapter for VMware.
Choose the Subnet option, and you will see a dialog where you can change the network range:
Once you have changed the network here, you can click the OK or Apply buttons, and after a few seconds it will update.
