title: Finding addresses of next hop
body: <p>I have the next table:</p>
  
  <pre><code>Network adress    NetMask         Next Hop
  128.96.166.0      255.255.255.0   1
  128.96.166.0      255.255.252.0   2
  0.0.0.0           0.0.0.0         3
  </code></pre>
  
  <p>I want to find the adreeses range, for which the router will send to each Hop. for example, the adress's IP: 128.96.166.0 would send to Hop 1. </p>
  
  <p>I don't understand  how the NetMak help me to detrmine it. Is it not always would go to hop 1?</p>
