First of all I want to comment on the Tags you've used. In the Subject and body of the OP you say VMware Workstation 8 yet in the Tags: you have "6.0.2, vmware_workstation_6, 3.5, 6.5, 6.5.1, 6.5.0, 6.5.2, 6.5.3" so which is it? From the Tags it would appear you're using VMware Workstation 6 however the information I'm presenting is, although not exclusively, for VMware Workstation 8. (This should also apply to v7 and v9 and probably v6 as well.)
Have a look at chapter 5 "Configuring Network Connections" in the Using VMware Workstation 8 (PDF). (If using v6 then see chapter 13 in VMware Workstation 6 User's Manual (PDF))
Looking at DHCP Conventions for Assigning IP Addresses in Host-Only and NAT Networks you'll see what André is referring to, net.1assigned to the Host machine e.g. 192.168.0.1, however it is not carved in stone that net.1 can only be used for the Host machine however this cannot be changed in the Virtual Network Editor and manually assigning it in the Network Adapters Properties in Windows in the Host in order to use net.1 in the Guest one will still need to edit the vmnetdhcp.conf file to properly reflect changes made in the Network Adapters Properties in Windows in the Host. This of course assumes one is using a Host Adapter for the target VMnet. Have a look at my replies to VMware Player 4 - Configuration Help as a reference example.
Anyway once you've either removed the Host Adapter for the target VMnet in the Virtual Network Editor or assigned a different net.x address for the Host Adapter for the target VMnet in the vmnetdhcp.conf file then your are free to use net.1 for a Virtual Machine's Network Adapter.
Also while this is doable, as I do it often when building customized test virtual networks, I do not know that it is officially supported however it does work when all things are configured properly.
