How It Works:
- Get-DnsClientServerAddress returns the configured DNS servers for every network adapter, across both IPv4 and IPv6 - by default this includes the loopback interface and empty entries, which aren't useful for a quick check.
- -AddressFamily IPv4 filters down to only IPv4 DNS entries.
- Where-Object { $_.InterfaceAlias -notlike "*Loopback*" } excludes the loopback interface, keeping only the real network adapter.
- Select-Object InterfaceAlias, ServerAddresses trims the output down to just the adapter name and its configured DNS server(s).
