To get all network adapters and their DNS information using PowerShell, you can use the Get-NetAdapter cmdlet from the NetAdapter module to retrieve a list of network adapters, and the Get-DnsClientServerAddress cmdlet to retrieve the DNS server addresses for each adapter.
# Import the NetAdapter module
Import-Module NetAdapter
# Get a list of all network adapters
$Adapters = Get-NetAdapter
# Loop through the adapters
foreach ($Adapter in $Adapters) {
# Get the DNS server addresses for the adapter
$DnsServers = Get-DnsClientServerAddress -InterfaceAlias $Adapter.Name
# Create a new object with the adapter and DNS server information
$Object = [pscustomobject]@{
Adapter = $Adapter.Name
DnsServers = $DnsServers.ServerAddresses -join ','
}
# Write the object to the console
$Object | Format-Table -AutoSize
}But this doesn’t let you work with the data so we can change the $object and return it into a Variable like this
# Import the NetAdapter module
Import-Module NetAdapter
# Get a list of all network adapters
$Adapters = Get-NetAdapter
# Loop through the adapters
$AdapterInformation = foreach ($Adapter in $Adapters) {
# Get the DNS server addresses for the adapter
$DnsServers = Get-DnsClientServerAddress -InterfaceAlias $Adapter.Name
# Create a new object with the adapter and DNS server information
$Object = [pscustomobject]@jamilpremji
Adapter = $Adapter.Name
DnsServers = $DnsServers.ServerAddresses -join ','
}
# Write the object to the console
$Object
}When returning something in PowerShell, it returns anything that is written to the pipeline.
Keep in mind that a function can return multiple values or objects by writing them to the pipeline or by using the return keyword. You can use the Out-Default cmdlet to write the output to the console or the Out-File cmdlet to write the output to a file. You can also use the > operator to redirect the output to a variable or to a file.
