Hi Sufiyan Shaikh,

Thank you for posting your query in Microsoft QnA !

You can use below script to get all the Subnet details :

Connect-AzAccount 
# Get all virtual networks in the subscription
$vnetList = Get-AzVirtualNetwork

foreach ($vnet in $vnetList) {
    Write-Host "Virtual Network: $($vnet.Name), Resource Group: $($vnet.ResourceGroupName)"

    # Get all subnets in the virtual network
    $subnetList = Get-AzVirtualNetworkSubnetConfig -VirtualNetwork $vnet

    foreach ($subnet in $subnetList) {
        Write-Host "  Subnet Name: $($subnet.Name), Address Prefix: $($subnet.AddressPrefix)"
    }

    Write-Host ""
}

You can modify the same to achieve your specific use case.

Hi Sufiyan,

$vnet = Get-AzVirtualNetwork
$vnet.Subnets | Format-List

Additionally This alternative code get the subnets Ids and others details modifying the $network.[Information that you need] , also you can update if you want for specific resource with a filter when you get vnets:

$vnet = Get-AzVirtualNetwork

foreach ($network in $vnet)
{
    $subnets = $network.Subnets
    foreach ($subnet in $subnets)
    {
        Write-Output $subnet.Id
    }
}
