PortScan shows all open ports and additional information like host name,  MAC address, HTTP, SMB, FTP, iSCSI, SMTP and SNMP services. It uses up  to 100 threads for scanning large IP addresses. You can search for UPnP  enabled devices, Bonjour services, Netgear router, Samsung printer and  Freecom network devices. So you can find them even if you don’t know the  ip address.
