network, gateway, subnet mask, and IP.... What is 'network' for?
I am trying to set up my first colocated server. It is running linux - CentOS 4.1.
My colocation facility sent me the following 4 pieces of information:
network (single IP address)
gateway (single IP address)
IP range (5 consecutive IP addresses)
My problem is that I don't know what the network IP address is for. When I configure CentOS to use a static IP I just choose the first of the 5 IP addresses they sent me to use as the IP of the server, and then I supplied the gateway and subnet mask when prompted. But there was never any place for the 'network' address.
So what is this address for? I can't get networking to work so I am thinking that this is somehow related.
When I do ifconfig it sees eth0 and it has the right IP and gateway and subnet mask, but I can't see the machine on the network and I can't get to anyplace out on the network from my machine.
