No it doesn't - set the realserver loopback interface address as per
normal, then edit the registry to change them from 255.255.255.0 to
255.255.255.255.

Unfortunately I forget exactly where the key is buried, but I suspect it
will be somewhere within:

HKLM\SYSTEM\CurrentControlSet\Tcpip\Parameters\Interfaces\{SID_VALUE}

An alternative is to set the netmask to 255.0.0.0, since a more specific
route for the local net will already exist and will be favoured over it;
this can however cause unexpected problems for inter-real-server
communication.
