Discovery Profile IP Ranges

When you create or edit a discovery profile, you can enter the IP address ranges you want to discover for IPv4. Range discovery is not supported for IPv6 addresses.

When specifying IP ranges in the discovery profile, the following rules apply:

An IPv4 range can contain wildcards (*). A wildcard represents a full range for an IP octet: 0-255.
An IPv4 range can contain hyphens (-). A hyphen can exist between the lower IP address and upper IP address. A hyphen can also be in the IP octets in the lower IP address.
If a wildcard or a hyphen is used in a term in the lower IP address, the upper IP address cannot be represented.

Examples: Valid IP Ranges

Both of the following examples attempt to discover devices at every IP address from 10.25.1.0 to 10.25.1.190:
```
10.25.1.0-10.25.1.190
```
OR
```
10.25.1.0-190
```
Both of the following examples attempt to discover devices at every IP address from 10.25.0.0 to 10.25.255.255:
```
10.25.*.* 
```
OR
```
10.25.0.0 - 10.25.255.255
```
Both of the following examples attempt to discover devices at every IP address from 10.25.0.3 to 10.25.0.40 and from 10.25.1.3 to 10.25.1.40:
```
10.25.0-1.3-40
```
OR
```
10.25.0.3 - 10.25.0.40, 10.25.1.3 - 10.25.1.40
```
Both of the following examples attempt to discover devices at every IP address from 10.25.0.0 to 10.25.0.5, from 10.25.1.0 to 10.25.1.5, and so on, up to 10.25.255.0 to 10.25.255.5:
```
10.25.*.0-5
```
OR
```
10.25.0.0 - 10.25.0.5, 10.25.1.0 - 10.25.1.5 ... 10.25.255.0 - 10.25.255.5
```

Examples: Invalid IP Ranges

The following example is invalid because the upper IP address is incomplete:
```
10.25.1.0 - 10.23
```
The following example is invalid because when a hyphen (-) is used in an octet in the lower IP address, the upper IP address cannot be present:
```
10.25.1.0-190 - 10.25.1.255
```
The following example is invalid because when a wildcard (*) is used in an octet in the lower IP address, the upper IP address cannot be present:
```
10.25.*.0 - 10.25.255.255
```
The following example is invalid because it is unclear whether the wildcard octet (1*) implies 10.25.10-19.0 or 10.25.10-199.0:
```
10.25.1*.0
```
