I have been asked to setup a secondary address in the range of 225.168.xxx.xxx  and found out if was invalid.   Why is this an illegal ip space and how can I find out more about it?   Google searches have not turned up anything as of yet.


Thanks

Hi

Sorry

You cannot use this ip address for normal assignment which is reserved for multi casting.

Great help guys ... before I accept and close can I ask for a bit more clarification?  In the Guide posted by Moon Blue69 it says

3.8.4 Class D And E Addresses
Class D networks are used for multicasting and do not contain network or host IDs. Multicasting is the process of sending a message simultaneously to more than one destination on a network. The first octet of a Class D address ranges from 224 to 239.
       Multicasting is often used to send information simultaneously to several registered hosts. A computer will register itself using a Class D address.


How do you register a computer with a Class D address if you cannot assign it to a NIC?

You will have a class D ip address on multicast and you add the ip address of the participients of the multicast. You cast to one IP that is class D and the all the listed participients will recive it.

Hope this clarified it
