Description

The Get-IpamIpAddressAuditEvent cmdlet gets all IP address audit events from an IP Address management (IPAM) server over a time interval. IPAM enables IP address tracking through correlation of Dynamic Host Configuration Protocol (DHCP) lease events on managed DHCP servers with user and computer authentication events on managed domain controllers and Network Policy Server (NPS) servers. You can search correlated events by IP address, client ID, hostname, or username. Use DCHP events between a start date and an end date to correlate data. The data returned includes data for both the start date and the end date.

The cmdlet returns only the top 10,000 rows if the query results exceed more than 10,000 rows. The cmdlet will display a warning if this occurs. You can avoid this situation if you narrow the search criteria to limit the results.

Examples

Example 1: Get all IP address audit events

PS C:\> $Today = Get-Date
PS C:\> $LastMonth = $Today.AddDays(-30)
PS C:\> $IpamIpAddressAuditEvents = Get-IpamIpAuditEvent -StartDate $LastMonth -EndDate $Today

The first command gets the current date and stores the result in the variable named $Today. The second command subtracts 30 days from the date stored in the $Today variable and stores the result in the variable named $LastMonth. The third command gets all IP address audit events between the date stored in the $LastMonth and the date stored in the $Today variables. The command gets only DHCP lease data. The command stores the results in the variable named $IpamIpAddressAuditEvents.

Example 2: Get all IP address audit events for an end date and a start date

PS C:\> $Today = Get-Date
PS C:\> $LastMonth = $Today.AddDays(-30)
PS C:\> $IpamIpAddressAuditEvents = Get-IpamIpAuditEvent -StartDate $LastMonth -EndDate $Today -IpAddress 10.10.1.1

The first command gets the current date and stores the result in the variable named $Today. The second command subtracts 30 days from the date stored in the $Today variable and stores the result in the variable named $LastMonth. The third command gets all IP address audit events for the specified IP address, between a start date and an end date and stores the results in the variable named $IpamIpAddressAuditEvents. This command searches only DHCP lease events.

Example 3: Get all IP address audit events, user events, and logon events for an end date and a start date

PS C:\> $Today = Get-Date
PS C:\> $LastMonth = $Today.AddDays(-30)
PS C:\> $IpamIpAddressAuditEvents = Get-IpamIpAuditEvent -StartDate $lastMonth -EndDate $Today -IpAddress 10.10.1.1 -CorrelateLogonEvents

The first command gets the current date and stores the result in the variable named $Today. The second command subtracts 30 days from the date stored in the $Today variable and stores the result in the variable named $LastMonth. The third command gets all IP address audit events for the specified IP address, between a start date and an end date. The command includes user and computer logon events from DC and NPS through the CorrelateLogonEvents switch parameter. The command stores the results in the variable named $IpamIpAddressAuditEvents.

Example 4: Get all IP address audit events by MAC address

PS C:\> $Today = Get-Date
PS C:\> $LastMonth = $Today.AddDays(-30)
PS C:\> $IpamIpAddressAuditEvents = Get-IpamIpAuditEvent -StartDate $LastMonth -EndDate $Today -ClientId "AA:BB:CC:DD:EE:FF" -CorrelateLogonEvents

The first command gets the current date and stores the result in the variable named $Today. The second command subtracts 30 days from the date stored in the $Today variable and stores the result in the variable named $LastMonth. The third command gets all IP address audit events for a client ID, between a start date and an end date. The command includes user and computer log-on events from DC and NPS through the CorrelateLogonEvents switch parameter. The command then stores the results in the variable named $IpamIpAddressAuditEvents.

Example 5: Get all IP address audit events by hostname

PS C:\> $Today = Get-Date
PS C:\> $LastMonth = $Today.AddDays(-30)
PS C:\> $IpamIpAddressAuditEvents = Get-IpamIpAuditEvent -StartDate $LastMonth -EndDate $Today -HostName "client1.contoso.com" -CorrelateLogonEvents

The first command gets the current date and stores the result in the variable named $Today. The second command subtracts 30 days from the date stored in the $Today variable and stores the result in the variable named $LastMonth. The third command gets all IP address audit events for a given hostname, between a start date and an end date. The command also includes user and computer log-on events from DC and NPS through the CorrelateLogonEvents switch parameter. The command stores the results in the variable named $IpamIpAddressAuditEvents.

Example 6: Get all IP address audit events by username

PS C:\> $Today = Get-Date
PS C:\> $LastMonth = $Today.AddDays(-30)
PS C:\> $IpamIpAddressAuditEvents = Get-IpamIpAuditEvent -StartDate $LastMonth -EndDate $Today -HostName "client1.contoso.com"

The first command gets the current date and stores the result in the variable named $Today. The second command subtracts 30 days from the date stored in the $Today variable and stores the result in the variable named $LastMonth. The third command gets all IP address audit events for a username, between a start date and an end date. Since the username is available only from authentication data, this data is always included while querying for audit events based on username. The command stores the results in the variable named $IpamIpAddressAuditEvents.

Required Parameters

-ClientId

Specifies an array of client IDs. Use this parameter to search for audit events by Media Access Control (MAC) address. You may use dashes (-) in the client ID but they are not required.

Type:String
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-EndDate

Specifies the end date, as a DateTime object, for which to get the event data. To get a DateTime object, use the Get-Date cmdlet and specify the date in DD/MM/YYYY format.

Type:DateTime
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-HostName

Specifies an array of host names. Use this parameter to search correlated events by host name.

Type:String
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-IpAddress

Specifies an IP address. Use this parameter to search correlated events by IPv4 address. The cmdlet does not support IPv6 address tracking.

Type:String
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-StartDate

Specifies the start date as a DateTime object. To get a DateTime object, use the Get-Date cmdlet and specify the date in DD/MM/YYYY format.

Type:DateTime
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-UserName

Specifies an array of user names. Use this parameter to search correlated events by username. Searching by user's domain name is not supported. Logon events are included in this search because user names are not specified in DHCP lease events.

Type:String[]

Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False

Optional Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CorrelateLogonEvents

Indicates that the cmdlet correlates logon events. Use this parameter to include or exclude user and computer events from domain controllers and NPS servers. If you specify this parameter, logon events are included in the correlated set of events retrieved by this cmdlet.
