CIDR is based in the definition of net-id prefix of<br />
any size.<br />
The first level assignment authority is IANA. There<br />
are 5 RIR (Regional Internet Registry) that spread<br />
<strong>addressing</strong> space among minor entities.<br />
CIDR uses VLSM to define arbitrary size sub-nets.<br />
With CIDR, the routers must change the way the<br />
use their routing tables, all address requires<br />
always a mask.
