Hi!<br />
<br />
Problaby this question is lame, but anyway...<br />
<br />
Here is some entries from Cisco IOS routing table:<br />
* &nbsp;16.0.0.0/12 &nbsp; &nbsp; &nbsp;146.188.x.x &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 0 702 8220 1889 1889 i<br />
*&gt;i &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 193.156.x.x &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;5 &nbsp; &nbsp;100 &nbsp; &nbsp; &nbsp;0 8220 1889 1889 i<br />
*&gt; 16.0.0.0 &nbsp; &nbsp; &nbsp; &nbsp; 146.188.x.x &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 0 702 701 33 i<br />
<br />
For the first enrty '16.0.0.0/12' network mask is clear -&gt; 12, but for third entry threr is no mask. <br />
So the question is, How wide is network portion of IP address if no network mask specified?<br />
<br />
thanks in advance.
