3. What is Automatic Subnet Scanning?
» SolarWinds IP Address Manager (IPAM) allows you to perform
automated IP address scans on all your subnets with custom intervals.
 Easy to create your own scan job from scratch. Each job performs a scan of network
devices based on subnet.
 You can automate IP address scanning for all your subnets, a group of subnets, or for an
individual subnet.
» There are 3 scanning modes used to scan IP addresses:
 ICMP scan (ping sweep)
 SNMP scan
 Neighbor scan (using ARP tables)
» SolarWinds IPAM is an effective IP scanner tool that allows you to
periodically scan a subnet.
 Flexibility to run scans as frequently as every 10 minutes, or as infrequently as every 7
days based on your requirements.

4. #1 Configuring Automatic Subnet Scanning
» SolarWinds IPAM is capable of using both SNMP and ICMP scanning to
continuously determine the status of your monitored network.
» You can configure the scan while adding a new subnet, or by editing the
properties for any existing subnet.
 On the Manage Subnets & IP
Addresses tab, select the subnet(s)
for which you want to automate
the scan
 On the right pane, click Edit to
open the Edit Subnet Properties
window.
 You can enter the Scan Interval
field to set the automated scan
frequency (in minutes, hours or
days) between 10 minutes and 7
days.

5. #2 Configuring Neighbor Scanning
» SolarWinds IPAM solution has another type of scan called Neighbor
Scanning, which will attempt to retrieve the status of a device that may
not be responding to ICMP by scanning the ARP table of a neighbor
router to determine what IP addresses are active.
» It is disabled by default. When you un-check it, additional options will
appear where you can add the IP Address of the neighbor device and
select a Scan Interval.

6. #3 Managing Subnet Scan Settings
» Scheduled IP address scanning also helps avoid IP address conflicts by
recognizing transient IP status.
 For example:
• If a static IP goes offline during a maintenance update and is not reachable,
SolarWinds IPAM will configure that IP as “transient” to prevent other network
engineers from assigning it.
• You can configure the transient period for any number of consecutive days, up to a
year. Upon a subsequent scan, if the network device returns online again, IPAM will
simply show its associated status as "used."
» SolarWinds IPAM continuously scans all managed IP addresses on your
network.
 If a device fails to respond to any SNMP or ICMP requests for the period of time
designated as the Transient Period, IPAM changes the status of the unresponsive IP
address from “used” to “available”.

7. #3 Managing Subnet Scan Settings (contd.)
» You can provide an appropriate value for the Transient Period (which must be a
value from .2 to 340 days) in the Duration (days) field.

» If you want to customize the Transient
Period settings further, click inherit
values from Subnet Scan Settings
» This will open a new browser window
with advanced Subnet Scan Settings
where you can specify ICMP and SNMP
scanning thresholds.
