I connect to vm images using IP. I use Bridged Networking. Why does your IP change? DHCP? That is a problem with vmware. To have a fixed IP you need a real MAC address which you don't really have with VMWare (although you can manually override within a fixed range). You can, however, have your DHCP server not use a certain range or reserve an IP for a dummy MAC and then use a manually configured fixed IP in the vm.
