Setting individual IP addresses for Web testing

Question

Dear all,
I recently purchased an old MacMini to do some Web-application testing in a more convenient way than using a remote server.
Because the MacMini is a rather old model (first Core 2 Duo model), I installed MacOS 10.6.6 SnowLeopard Server on it.
I am, however, facing troubles to get it do what I wish.
The IP address of the machine is : 192.168.1.42
I wish it to respond to the following addresses :
192.168.1.100 for website svenskaklubben.be
192.168.1.101 for website schumantrophy.eu
192.168.1.102 for website sky-project.com
Etc ...
These sites do not have to be accessible from the outside : they are LAN only for testing.
The default configuration with only one site works perfectly, but things do change when I add several websites.
When I setup the zones in the DNS part of the server, the best result I can achieve is that a trace (or ping) on the name returns the IP correctly.
But when I ping (or trace) the IP, it always says : "host not found", or "host down"
Most probably, I do mess up somewhere.
Any help to guide me step-by-step would be highly appreciated, since I'm working on this since a couple of days and start to loose my nerves :-)
Lots of thanks in advance

Oh well ...
I followed the instruction on your pages, and indeed it clarified some points.
I could have the DNS working (I think), since the dig command returned the following results, reflecting several modifications as well (those results were obtained through a client machine on the network) :

HOWEVER, i was still totally unable to get it working with a VirtualHost set in the "sites" part of ServerAdmin.
Ping returns :
ping: sendto: No route to host
ping: sendto: Host is down
ping: sendto: Host is down
While TraceRoute returns :
Traceroute has started…

Interesting, though, is the fact that the IP address seems to be correctly resolved in the Traceroute ...
