title: How to convert hexadecimal encoded string to hexadecimal integer
body: <p>So basically what I'm trying to achieve is to get a MAC address from a text file and increment the value by one.</p>
  
  <p>Been bashing my head against the Google/StackOverflow wall for a couple of hours, think there's a concept I'm just not getting.</p>
  
  <p>PowerShell:</p>
  
  <pre><code>$Last_MAC_Address = (Get-Content -LiteralPath "\\UNC\Path\Last MAC Address.txt")
  
  Write-Host ($Last_MAC_Address)
  # Output: 00155DE10B73
  
  $Next_MAC_Address = (($Last_MAC_Address | Format-Hex) + 1)
  </code></pre>
