# DiscoveryAPI- Scoped

The DiscoveryAPI class provides methods that launch a quick discovery of a single IPv4 address and return summaries of previously launched discovery statuses for a single configuration item \(CI\) or for all scanned CIs.

This class runs is in the `sn_discovery` namespace.

**Parent Topic:**[Server API reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/api-server.md)

## DiscoveryAPI - discoverIpAddress\(String ipAddress, String application, String source\)

Discovers a specified IPv4 address.

A MID Server is selected automatically, based on the IP address provided or the application specified.

## DiscoveryAPI - reportCiIpAddressStatus\(Object ipAddress, Object discoveryStatusSysId\)

Used to return a summary of a configuration item's Discovery status given the specific status sys\_id and IPv4 address.

The following exceptions can be thrown:

-   **DiscoveryStatusNotFoundException**: `Displays this message: Discovery Status with sys id '<invalid value>' does not exist`
-   **DiscoveryDeviceHistoryNotFoundException**: `Device History with Discovery Status sys id '<invalid value>' and ipAddress '<invalid value>' does not exist`
-   **IllegalArgumentException** \(invalid input arguments\): This argument exception prevents input values from being null.
    -   `Discovery Status sys id can not be null`
    -   `ipAddress can not be null`
-   **IllegalArgumentException** \(values stored in database\): This argument exception prevents erroneous data from being returned to the caller in the case of bad attribute values.
    -   `Discovery Status 'state' property can not be null`
    -   `Device history 'source' property can not be null`
    -   `Device history 'issues' property is not an integer: <invalid value>`
    -   `Device history 'issues' property can not be less than 0: <invalid value>`

## DiscoveryAPI - reportCiStatus\(Object discoveryStatusSysId\)

Used to return a summary of a CI Discovery status given a specific Discovery Status sys\_id.

The following exceptions can be thrown:

-   **DiscoveryDeviceHistoryNotFoundException**: `Device History with Discovery Status sys id '<invalid value>' and ipAddress '<invalid value>' does not exist`
