SharePoint NLB multiple Web Applications

Hi  , For WFE network loadbalancing, how do you add 3 new web applications to be load balanced?
Based on my testing it appears that for each Web Applications in my 2 WFE setup, I will need the following:
So WFE 1 will have 3 IPs and WFE 2 will also have 3 IPs.
Each WFE will have to have 3 IPs for the 3 Web Applications.

Is this assumption correct?

It appears that i will have to get 3 NICs for each WFE server.
or
Can I get a Virtual NIC, or assign more than one IP to a NIC card?

in our NLB setup, we have the following:

2 WFE servers, running NLB - each of the WFE servers does have 2 nics and 3 IP addresses
 - NIC 1 is controlled by the NLB
 - NIC 2 is used by the server so that I can access it using its netbios name - I think there may be a way around this (eg by using multicast instead of unicast in the cluster parameters, but my network guys wanted us to use unicast so they didn't have to muck around configuring routers or something, possibly other methods as well?)
 - NIC 1 has an ip address
 - NIC 2 has an IP address
 - the third IP address is the address of the NLB - it is this address that we point all of our DNS entries to for our web applications

When hosting different web applications, we create a DNS entry which points to the NLB IP address. IIS is configured to use the host headers so it knows which site we have requested. We are hosting 10 or more web applications - you don't need to get an IP address for each web application using this method.

Hope this helps!
