PortScan::Scan and identify network devices
PortScan can find all active devices on your network. Discover the IP address and available services for each network device. Run a speed test to check your internet connection speed.
PortScan shows all open ports and additional information like host name, MAC address, HTTP, SMB, FTP, iSCSI, SMTP and SNMP services. Up to 100 threads are used for scanning large ip address ranges.
You can search for UPnP enabled devices, Bonjour services, Netgear router, Samsung printer, HP printer (SLP / Service Location Protocol), MSA network devices, Freecom network devices and IPv6 devices. So you can find them even if you don%u2019t know the ip address.
PortScan can ping any computer with 3 standard sized ping packets, with 3 different sizes, each 10 times or ping the computer continuously. A graph shows the distribution of response times.
