  • With the IP Selection Method, choose whether you want to enter a Class C base IP with start/end (IPv4), a List of individual IPs (IPv4), IP and Subnet (IPv4), or an IP with octet range (IPv4). If you want to discover an IPv6 network, you can provide a list using the List of individual IPs (IPv6) option. All of these methods result in a number of IP addresses that will be scanned during the auto-discovery process. Based on your selection above, different setting fields are available.
  • We recommend you leave the Class C base IP option. In the IPv4 Base field, enter the first three octets of your network's IP range, for example 192.168.0 or 10.0.0, or whatever IP address range you use. If you don't change the values for IPv4 Range Start and End, PRTG will automatically complete the IP base and scan all IP addresses ending in .1 to .254.
  • If available, provide credentials for Windows Systems, Linux Systems, VMware/XEN Servers, and for SNMP Devices. You can show the respective settings by removing the check mark symbol at the beginning of the respective line. Find more information in the Auto-Discovery section.
  • Keep the default values for all other settings.
  • Click the Continue button.

Ready

PRTG will now start discovering your network in the background, adding devices and sensors automatically. Meanwhile, you can get familiar with the Ajax web interface.
