According to a Microsoft developer that I spoke with last week, NT 
3.5.1 can be hacked with the known registry edit hack to allow up to 
254 IP addresses/nic. NT 4.0 can support up to 500/nic. He said that 
several ISPs were already rolling out the NT 4.0 solution. Given that 
UUNet is 13% owned by Microsoft I would venture to say that they are 
probably the first to roll out these features and you might be able to 
get more information from them.

Hey y'all.

I still haven't seen a response to this in the list so I'm sending it 
again. If any you know about multihoming NT, please respond.

Whooah! Is this NT3.5x? My documentation says that I can configure up
to five IP addresses per network interface. The word out on the net 
is
that you can hack the registry to give you something like 10 - 16
addresses. It is said that anything more than that is asking for
trouble.

If there is a way to have up to 254 IP's per interface I would very
much like to know what it is. Also, what is the server load for this
type of thing? If 254 is the theoretical max, what is the practical
max, assuming a 64M RAM 586 serving HTTP.

Geoff.
