Why have certain address range been chosen as private
|
|
|
| Hi y'all
Class A address range 10.0.0.0
Class B address range 172.16.0.0 - 172.31.0.0
Class C address range 192.168.0.0
are all reserved for private use and should NOT be propagated across public networks.
Yeah, you know that; but does anyone know why these address ranges were chosen.
Look at that!
Cheers

| Hi Hippo;
There are two primary reasons that the "private" IP ranges were created:
1)hosts that do not require access to hosts in other networks or the Internet in general, but still require the hierarchical structure; and
2)hosts that only require limited access for such apps as e-mail, remote login, etc. For much of this, the host would be going through a gateway at any rate.
If you want to read the full rfc on this, the address is: www.ietf.org/rfc/rfc1918.txt
Hope this helps;
