ip addressing

[richardwt]

what address range has the fewest hosts according to cisco.
some pratice exams say c others say d which is correct for the ccna

This is an IP forum, not a CCNA practice area Richard - if you need help post the question. Most people here have never looked at CCNA and those that have won't recall whether the answer is c or d...

Richard it actually depends on how the question is phrased. Of course a class D address has the fewest host addresses but is not used as a public address. A class C would be the next one up that is a public address range. I know I had the same question on my test and Class D wasn't even listed on it. Good luck in your testing. david e

Hi,

Class D addresses consist of binary 1110 plus 28 bits for multicast group addresses. As such, they don't really compare with the other classes at all. See -->

apols, thought c and d were multiple choice answers.

i have a question. How a machine knows that tcp/ip adress is from your network or not

 

[sobak]

Ispires, boils down to the network mask...

192.168.1.0
255.255.255.0

Any address that is on the network would be between 192.168.1.1 - 254 (0 being the network address and 255 being the broadcast address).

A packet going to 192.168.2.1 would not be within that range then the system would send it to the default gateway (if setup for one).

The tricky part is when you start subnetting.

192.168.1.0
255.255.255.248

The above conbination would give you 32 possible networks with 6 hosts (computers) per network. Your networks would be between 192.168.1.0 -254. Each network would look like this....

192.168.1.0 (network) 192.168.1.1 - 6 (computers)

So 192.168.1.2 and 192.168.1.9 would be on totally different networks (have I blown your mind yet?)

TCP/IP is hard to go into detail in this forum, suggest you take a class on TCP/IP if you want to learn more about subnetting but to answer your question....

The computer uses the subnet mask to determine if the packet stays on the network or is going to a different network.
