Please explain in detail why the all zeros and all ones subnets are not used.

Help needed as soon as possible. :)

Re: IP Addressing 15 years 2 months ago #689

These addresses are reserved.

All zeros mean that the address is for this network or highway only.

All ones are used as a broadcast to all hosts on the network or highway.

Hope this is detailed enough!

Re: IP Addressing 15 years 2 months ago #703

The answer above is correct, but since you said in detail.. the best places to look are the RFCs
www.ietf.org/rfc.html

or even better.. this little cisco document i dug up for you ;)
