# Port Package
You can choose the IP of a specific country, with a retention time range of 3 to 30 minutes.
**Account and Password Mode**
1\. Enter the operation console (Dashboard), click on the menu Dynamic Traffic - Port Package, and you can see the purchased ports.
2\. Click "Edit", set the required username, password, country/region, rotation cycle, and format, and then click "Confirm Modification"
3\. During use, you can copy the host name: port, username, password or the IP command, and paste it into the fingerprint browser or any program that supports HTTP or Socks5 IP.
**White list mode**
1\. Click on the white list mode
2\. Click "Edit", enter the IP addresses that need to be authorized (support batch addition; multiple IPs should be separated by commas), and then click "Save"
