Same Network Card - Multiple IPs

Is this possible?

With access to a range of IPs - say 4 - will I be penalised for having the same network card look at thos different IP addresses - thereby actually hosting in the same place?

If these sites were then interlinked, would I be ok on the basis of interlinking between separate IPs, or will it be penliased?

I find that unlikely, put it this way do you think ISP will just use one IP address on one network card for their server.

I doubt it!

I have a Class C Ip set (256 ip address) they all come into one Router and one network Card. the Ip addresses are then shared among different servers in different locations across yorkshire .

Nobody outside your network will be able to tell if two IPs are going to the same or different machines.

But they can tell that you have a lot of linking going on between hosts with the same IP prefix.

From a pure IP address it does not make a blind bit of difference. Even at a WAN level, routers use their own MAC address.

When the IP header gets stripped off, you are dealing with layer 2 frames and not IP packets, so even if your host has more than 1 IP address who cares? Thats the nature of VLANS the wire speed switching technology deployed world wide.

Conclusion - your safe;)
