Port Scanner

App for scanning network ports.

Supports IPv4 and IPv6. You can scan multiple IPs and ports at once, set port ranges, even combine IP versions.

Found ports are associated with protocols they are assigned to according to iana.org (as found in May 2018), so you can view, what kind of application probably uses the port.

When selecting which IP addresses and ports to scan: add ranges with a hyphen ('-') character (e.g.: 192.168.0.1-192.168.0.254, 10-5120 for ports), separare individual addresses/ports and/or ranges with a comma (e.g.: 192.168.0.1,10.0.0.1-1.254,8.8.8.8, 10,40-50,80 for ports).

You don't have to specify a full second address when adding an IP range (e.g.: 192.168.0.1-2.254 will go through IPs 192.168.0.1 through 192.168.2.254).
