title: IPv6 link-local address format
body: <p>I am working on a project related to networking/compression. One of the machines is Windows Vista, which already has IPv6 configured.</p>
  
  <p>When I try <code>ipconfig</code>, I see an address in the following format: <code>fe80::9dc8:72fa:aacd:76e2%10</code></p>
  
  <p>But when I try to ping this machine from another with <code>ping fe80::9dc8:72fa:aacd:76e2%10</code>, I get the following error:</p>
  
  <p><code>Ping request could not find host fe80::9dc8:72fa:e327:76e2%10.</code><br> 
  <code>Please check the name and try again.</code></p>
  
  <p>Any ideas/comments are very helpful.</p>
