IP Addressing Question Practice -- Subnet
|
|
|
| Dear All,
Here is one IP addressing question for you to practice.
Say if you leased or purchased one ip 209.38.10.1 and your subnet mask is 255.255.255.240 (default subnet mask is 255.255.255.0 <== C Class),then answer the following subquestions?
1) how many subnets do you have?
2) how many hosts do you have in each subnet?
3) what is your valid subnet ip address?
4) what is your valid hosts ip address range?
5) what is your valid broadcast ip address for each subnet?
6) what is your broadcast ip adddress for your whole subnets?
P.S. If you can solve this one, you grasp enough , deeply knowledge of network part to pass CIW foundation exam.
Good luck and have a shoot.
Post answer in one week.
Regards,
Ted Wang

| Here is what I don't get. If you purchase a single IP -- how can you have a subnet mask of 255.255.255.240??? Unless the subnetting is internal???
Whenever I have been issued an external IP I have not been able to use the full range, just that number. Slightly confused...??? | |

Clarify my question....
Say you have leased one ip from ISP...but you need to subnet your own private network. The ip you leased is the gateway to communicate with the Internet. Those subnets ip addresses only exist in your own private LAN....clear?? That means after you get ip address for each computer, you need to put gateway address to the one you leased, in this example it is the ip address you leased.

1) Being a class C network it can have 2,097,152 subnets.
2) 254 hosts(nodes) per subnet.
3)209.38.10.0
4)209.38.10.1 - 209.38.10.254
