Description

The Get-NetIPv4Protocol cmdlet gets the global settings for IPv4 protocol configurations for the computer. If you do not specify any parameters, the cmdlet gets the IPv4 protocol configuration settings for all network connections for the computer. The cmdlet returns IPv4 protocol settings, such as the Internet Control Message Protocol (ICMP) setting, the default hop limit, the neighbor cache limit, and the multicast configuration.

Examples

Example 1: Get all IPv4 protocol configurations

PS C:\>Get-NetIPv4Protocol

This command gets the global settings for all the IPv4 protocol configurations for the computer. The default output for the cmdlet does not include all properties of the NetIPv4Protocol object.

Example 2: Output all settings for IPv4 protocol configurations

PS C:\>Get-NetIPv4Protocol | Format-List -Property *

This command gets the global settings for all IPv4 protocol configurations for the computer. The command uses the Format-List cmdlet to display all the properties in the output in the form of a table. For more information, type Get-Help Format-Table.

Parameters

-AddressMaskReply

Specifies an array of values for address mask reply. The cmdlet gets the IPv4 protocol configurations that have these values. Address mask reply specifies how the computer responds to ICMP address mask packets. The acceptable values for this parameter are:

  • Enabled. The computer responds to ICMP address mask packets.
  • Disabled. The computer does not respond to ICMP address mask packets.
Type:AddressMaskReply[]
Accepted values:Disabled, Enabled
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-AsJob

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

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

-DeadGatewayDetection

Specifies an array of values for dead gateway detection. The cmdlet gets IPv4 protocol configurations that have these values. Dead gateway detection is a feature that identifies gateways that are not operating properly and switches the computer to a new default gateway if available. The acceptable values for this parameter are:

  • Enabled
  • Disabled
Type:DeadGatewayDetection[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-DefaultHopLimit

Specifies an array of values for the default hop limit. The cmdlet gets the IPv4 protocol configurations that have these values. The default hop limit is the default value for the CurrentHopLimit property in the IP interface. The current hop limit is the value that the IP interface writes in the time-to-live (TTL) field in all outbound traffic. When routers forward a packet, they decrement the hop limit by 1 and discard the packet when the hop limit is 0.

Type:UInt32[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-DhcpMediaSense

Specifies an array of values for Media Sense. The cmdlet gets IPv4 protocol configurations that have these values.

Media Sense provides a mechanism for the network adapter to notify the protocol stack of media connect and disconnect events. These events trigger the DHCP client to take an action, such as attempting to renew a DHCP lease or removing routes that are related to a disconnected network. When Media Sense is enabled, the network parameters on the laptop of a roaming user are automatically and transparently updated without requiring a restart when the user moves from one location to another. The acceptable values for this parameter are:

  • Enabled
  • Disabled
Type:DhcpMediaSense[]
Accepted values:Disabled, Enabled
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-GroupForwardedFragments

Specifies an array of values for group forwarded fragments. The cmdlet gets IPv4 protocol configurations that have these values. Group forwarded fragments specifies whether the IP interface collects fragments into groups before it forwards the fragments. The acceptable values for this parameter are:

  • Enabled. The IP interface collects IPv4 protocol fragments into groups before it forwards the fragments.
  • Disabled. The IP interface does not collect IPv4 protocol fragments into groups before it forwards the fragments.
Type:GroupForwardedFragments[]
Accepted values:Disabled, Enabled
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-IcmpRedirects

Specifies an array of values for ICMP redirects. The cmdlet gets IPv4 protocol configurations that have these values. ICMP redirects specifies whether to update the path cache in response to ICMP redirect packets. The acceptable values for this parameter are:

  • Enabled. The IP interface updates the path cache in response to ICMP redirect packets.
  • Disabled. The IP interface does not update the path cache in response to ICMP redirect packets.
Type:IcmpRedirects[]
Accepted values:Disabled, Enabled
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-IGMPLevel

Specifies an array of values for the Internet Group Management Protocol (IGMP) level. The cmdlet gets IPv4 protocol configurations that have these values. The IGMP level specifies the level of multicast support. The acceptable values for this parameter are:

  • None
  • SendOnly
  • All
Type:MldLevel[]
Aliases:MldLevel
Accepted values:None, SendOnly, All
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-IGMPVersion

Specifies an array of the IGMP version numbers. The cmdlet gets IPv4 protocol configurations that have these IGMP version numbers. The IGMP version is the maximum IGMP version supported by the host of IPv4 protocol configuration.

Type:MldVersion[]
Aliases:MldVersion
Accepted values:Version1, Version2, Version3
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-MediaSenseEventLog

Specifies an array of values for Media Sense event log. The cmdlet gets IPv4 protocol configurations that have these values. Media Sense event log specifies whether the computer logs DHCP Media Sense events. The acceptable values for this parameter are:
