IP assignment for virtual webhosting

Yes, that exactly the way we do it. If I imagine the power needed to
implement this its nearly impossible to reimpleent for ONLY name-based
Virtual Hosts. And if you think of Bandwith management - i don't see any
way to do this on an per name-basis, only per ip (and service) is possible
as far as I know. To use Bandwidth mangement on named vhosts-basis, you
would have to read out the FULL ip-header and service-specific headers on
the router...i think this is not possible without enormous CPU-power and
would give high delays on the router.

Same over here. We have built our own database-driven system over the last
years which links IP adresses to customers, measures their traffic and
even has the ability to traffic-shape groups of IP adresses to a certain
bandwith, like a Packeteer box can do.

Input comes from the border router which has IP accounting. Ofcourse when
customers want more than one hostname linked to the same virthost (but
with different content) we use a name-based virthost.

Because of this system it is very hard to implement name-based virtual
hosting, all accounting is done on one IP adress then and we have to
rethink our accounting scheme of virthosts (which takes time, costs money
etc. etc.)
