I need some clarification to the text book that I'm studying, please! The book says, "subnet masks permit you to suballocate network addresses." The example used is: class C address: 205.101.55 default subnet mask: 255.255.255.0 Q. When a person acquires an IP address, is he given just the netid portion of the IP, or both the netid & hostid? I ask this because the textbook example now jumps to using: subnet mask: 255.255.255.224 I understand that there are only 8 common subnet mask octets used, but Q. is it my choice which octet I choose, depending on the the number of network segments I require && the number of hosts on each segment? I can follow the example (255.255.255.224) above to the point of "seeing" that 6 subnets are available for the subnet mask of 11100000; and that the available hostids will range from 1-30. I just can see how I would determine which of the 6 available subnets (above) to use. Or can I use anyone one of the six that "works for me"?
