+# AssignedIPAddresses()
+
+**Applies to:**
+
+- [Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP)](https://go.microsoft.com/fwlink/p/?linkid=2069559)
+
+Use the `AssignedIPAddresses()` function to quickly obtain the latest IP addresses that have been assigned to a device. If you specify a timestamp argument, this function obtains the most recent IP addresses at the specified time.
+
+This function returns a table with the following columns:
+
+Column | Data type | Description
+-|-|-
+`Timestamp` | datetime | Latest time when the device was observed using the IP address
+`IPAddress` | string | IP address used by the device
+`IPType` | string | Indicates whether the IP address is a public or private address
+`NetworkAdapterType` | int | Network adapter type used by the device that has been assigned the IP address. For the possible values, refer to [this enumeration](https://docs.microsoft.com/dotnet/api/system.net.networkinformation.networkinterfacetype)
+`ConnectedNetworks` | int | Networks that the adapter with the assigned IP address is connected to. Each JSON array contains the network name, category (public, private, or domain), a description, and a flag indicating if it's connected publicly to the internet
+
+## Syntax
+
+```kusto
+AssignedIPAddresses(x, y)
+```
+
+## Arguments
+
+- **x**—`DeviceId` or `DeviceName` value identifying the device
+- **y**—`Timestamp` (datetime) value instructing the function to obtain the most recent assigned IP addresses from a specific time. If not specified, the function returns the latest IP addresses.
+
+## Examples
+
+### Get the list of IP addresses used by a device 24 hours ago
+
+```kusto
+AssignedIPAddresses('example-device-name', ago(1d))
+```
+
+### Get IP addresses used by a device and find devices communicating with it
+
+This query uses the `AssignedIPAddresses()` function to get assigned IP addresses for the device (`example-device-name`) on or before a specific date (`example-date`). It then uses the IP addresses to find connections to the device initiated by other devices. 
+
+```kusto
+let Date = datetime(example-date);
+let DeviceName = "example-device-name";
+// List IP addresses used on or before the specified date
+AssignedIPAddresses(DeviceName, Date)
+| project DeviceName, IPAddress, AssignedTime = Timestamp 
+// Get all network events on devices with the assigned IP addresses as the destination addresses
+| join kind=inner DeviceNetworkEvents on $left.IPAddress == $right.RemoteIP
+// Get only network events around the time the IP address was assigned
+| where Timestamp between ((AssignedTime - 1h) .. (AssignedTime + 1h))
+```
