Wellcome to our free online IPv6 port scan tool. The online port scanner allows you to scan a Domain or IPv6/IPv4 address for an open or closed TCP port.
How this tool working for domain: if you input domain - tool starting from IPv6 address lookup, if there is no IPv6 address available - it will try to find IPv4 address.
Finally you will see "Protocol type: IPv6" (it means that IPv6 address was found) or "Protocol type: IPv4" (if no IPv6 address).
This IPv6 port scanner will allow to scan up to ten ports per one click. There are three methods of ports input: 1) input ports as list, example "25, 44, 80, 433" 2) input ports as range, example "77-87" 3) field "or" unchanged and select "port:" from drop-down list, example "SMTP 25".
You also need to know that port number can be only from 0 to 65535.
