 ## Example
 
 Scan a specific Port-Range (1-500)
 
 ```powershell
-.\ScanPortsAsync.ps1 -IPv4Address 192.168.1.100 -StartPort 1 -EndPort 500 | Format-Table
+.\ScanPortsAsync.ps1 -ComputerName 192.168.1.100 -StartPort 1 -EndPort 500 | Format-Table

 ## ToDo
 [x] Integrate Port-List like: 80 (http), 443 (https), etc.
+[x] You can now enter a hostname as -ComputerName. The script will resolve the IPv4-Address.
