How to use

- Only ipv4 can be input.

- To distinguish between ip and ip, you have to press Enter.

- There is a limit of 1000 characters.

- In the input window, only “numbers”, “.”, and “:” can be entered.

- Therefore, if you \'paste (Ctrl+v)\' “KORNET DNS address 168.126.63.1”, only the IP address remains.

- If port is omitted, port 80 is assumed. To attach a port, enter '8.8.8.8:443'.
