The Get-NetNeighbor cmdlet gets neighbor cache entries. The cmdlet returns information about IP addresses and link-layer addresses for the neighbor cache entries.

The neighbor cache maintains information for each on-link neighbor, including the IP address and the associated link-layer address. In IPv4, the neighbor cache is commonly
known as the Address Resolution Protocol (ARP) cache.

Example 1: Get all neighbor cache entries

Example 2: Output all properties for neighbor cache entries

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

This command gets all the neighbor cache entries. 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.

Example 3: Get neighbor cache entries that have an IPv6 address

PS C:\>Get-NetNeighbor –AddressFamily IPv6

This command gets information about the neighbor cache for neighbors that have an IPv6 address.

Example 4: Get network adapters that have reachable neighbors

PS C:\>Get-NetNeighbor –State Reachable | Get-NetAdapter

This command gets a NetNeighbor object that contains neighbor cache entries that are reachable. The command passes the NetNeighbor object to the Get-NetAdapter cmdlet by
using the pipeline operator. The Get-NetAdapter cmdlet gets the network adapters that have the interface index number for the network neighbors stored the NetNeighbor object.
