You don't use more than one subnet in one single IP address. The IP address indicates what subnet you are in and a client may belong to only one subnet at a time.
An IP address range may indicate the presence of more than one subnet, however. This is done to split up a larger network into multiple smaller networks.
255.0.0.0 There is only one subnet allowed with this.
The subnet address for this ISP could be almost anything, depending on how the ISP breaks up a larger network pool into a smaller one. The default subnet would be 255.0.0.0, but that is not very likely with an ISP. You can check by using the 'ipconfig' command in Windows to see the subnet mask, or 'ifconfig' if using Linux.
This assumes you know how to subnet. On a network with 190.254.0.0 as a host address and using 11 bits for the subnet mask. The network address is 190.224.0.0 and the end of the range is 190.255.255.224. The address you show is within this range so cannot be the network address. If you don't know how to work this out manually use a subnet calculator such as the one on this URL: http://www.boson.com/FreeUtilities.html
Having more than one NIC on a computer can cause Internet connectivity problems if the correct configurations are not performed. For example, one should not allocate both NIC's to the same subnet.
How to find more than one address
No. 192.168.12.1 - 192.168.12.254 is one subnet (assuming 255.255.255.0 subnet mask)
no
It means the computer is set to get an IP address from a server (called DHCP) and it didn't get one.
yes it can
Local system IP address,Subnet mask and Default Gateway of a computer
Put one half of the network on a different subnet than the other half.
heck ya
