Presumably, all these internal server are on a LAN - there's no limit to the number of machines you can have on the LAN (apart from the hard-limit from the width of the address space). Note that I am NOT saying that your physical machine can handle an infinite amount of traffic - only that there is no limit defined by the protocol... I think your question is really about bandwidth (which is quite a separate subject) and is impossible to answer without knowing the expected traffic on each site. You could have a million webservers and proxy them over a dial-up modem - if no-one ever requests a page from them...
