II6 - 2 websites

Hi!

I have a cable modem with one static ip and a router and local network
running.

Now my questions:

I have two local lan IP addresses on the windows 2003 server bind to one
netcard.
My two websites show everyone to one local IP.

Now I want that my two website are accesible with two different ip's or
domains. How could I make that? Steps?
On my router I can forward http access to a computer in my local lan - what
must I there also configure?

Thanks!

You can have multiple domain names pointed to one IP, using Hostheaders you
can direct the domains to the folder of your choice for each domain. You can
have more then one domain name pointed to the same folder, but you can not
have one domain name pointed to multiple IPs doing so would probably confuse
DNS servers and could even create one major problem.

Hello,

The cheapest way to go is to use one IP, and host headers (buying IPs
usually costs some).

In the DNS server, set both websites to the public IP (your router). Then
forward all traffic on port 80 to the internal machine, and set up Host
Headers in IIS.

That is incorrect.

Actually, you can (and many larger web sites *do*) have multiple IP
addresses associated with a single domain name.

This is known as round-robin DNS and when used in conjunction with
load-balancing clusters can provide almost 100% availability.

Would this be done internally or externally to point to the multiple IP's?

I'm not sure I understand the question. Its normally implemented as a
load balancing solution for Internet-facing web servers which handle
high volumes of traffic and have geographically disperse sites which
all respond to a common FQDN.

Of course, those multiple IP's aren't all on the same physical
server... :)

No, that's right. Most probably quite a few separate physical
machines, or in the case of Hotmail no fewer than 3,000 'front-door'
boxes just for the web content and application alone !!
