How To Get Subnet ID In Azure PowerShell

To get Subnet ID in Azure PowerShell, we can use the Get-AzVirtualNetworkSubnetConfig command along with the complete script below.

$mySubnet = New-AzVirtualNetworkSubnetConfig -Name mySubnet -AddressPrefix "10.0.1.0/24"
$myvirtualNetwork = New-AzVirtualNetwork -Name test -ResourceGroupName MyNewResGrp -Location EastUS -AddressPrefix "10.0.0.0/16" -Subnet $mySubnet
$subnetConfig = Get-AzVirtualNetworkSubnetConfig -Name mySubnet -VirtualNetwork $myvirtualNetwork
$subnetId = $subnetConfig.Id 
Write-Output "Subnet ID: $subnetId" 

After executing the above query, I got the expected output, as shown below.

Subnet ID: /subscriptions/1cdf4300-dee5-4518-9c9c-feaa72a5cbd1/resourceGroups/MyNewResGrp/providers/Microsoft
.Network/virtualNetworks/test/subnets/mySubnet

You can see the same output as shown in the screenshot below.

OR, You can also use the Get-AzVirtualNetwork command along with the script below to achieve this.

$subnetId = (Get-AzVirtualNetwork -Name "test" -ResourceGroupName "MyNewResGrp" | 
             Select-Object -ExpandProperty Subnets | 
             Where-Object { $_.Name -eq "mySubnet" }).Id
             Write-Output "Subnet ID: $subnetId"

After executing the above query, I got the expected output, as shown in the screenshot below.

OR, We can also use the below query for this purpose.

$vnet = Get-AzVirtualNetwork -Name "test" -ResourceGroupName "MyNewResGrp"
$subnets = $vnet.Subnets | Select-Object Id
Write-Output "Subnet ID: $subnets"

After executing the above query, I got the expected output, as shown in the screenshot below.
