title: Format of snmpwalk instruction
body: <p>I'm working with SNMP and was given a command to use.  However, I'm trying to break it down into its components so I can understand if I need to change anything.  I've found documentation on pretty much everything except for the last part.  </p>
  
  <p>The command has this structure: </p>
  
  <pre><code>snmpwalk -v 2c -c communityname address.com .1
  </code></pre>
  
  <p>From my understanding the meaning of this structure is: </p>
  
  <p><code>snmpwalk</code> - command </p>
  
  <p><code>-v 2c</code> - specifies that the version is 2c, options are 1, 2c, 3</p>
  
  <p><code>-c communityname</code> - specifies the community name, which is like a password to an extent </p>
  
  <p><code>address.com</code> - the address of the computer in question </p>
  
  <p><code>.1</code>  - What is this ? I can't seem to find much documentation on it. </p>
