Curated Examples

Resolve DNS from PowerShell

Resolve DNS records through selected providers and transports.

This pattern is useful when you need a quick, repeatable resolver check.

It is adapted from DnsClientX.PowerShell/CmdletResolveDnsQuery.cs.

Example

Import-Module DnsClientX

Resolve-Dns -Name 'example.com' -Type A -DnsProvider Cloudflare

Resolve-Dns -Name 'example.com' -Type MX -DnsProvider Cloudflare, Google -ResolverStrategy FirstSuccess

Resolve-Dns -Name 'example.com' -Type TXT -ResolverEndpoint '1.1.1.1:53', 'https://dns.google/dns-query' -ResolverStrategy FirstSuccess

What this demonstrates

selecting a DNS provider explicitly
querying multiple providers with a resolver strategy
mixing endpoint styles without hardcoding internal resolver addresses
