Cheers @corey-alford, you ok if I use that and add it to the PSGallery?

Hey sorry missed the notification for this, yeah for sure. Would be cool if you could give me a credit on it or something but all good if too hard haha.

Hey @matt40k

I have also updated it as well so now you can use -type and it'll resolve those records when using Google or CloudFlare, updated version is below:

Resolve-DnsSSL -Domains <Domains Array> -Type <DNS Record Type> -Provider <CloudFlare, Google, Quad9>

Function Resolve-DnsSSL{
 param (
	[Parameter(Mandatory=$True)]
	[array]$domains,

	[Parameter()]
	[array]$Type = 'A',
 
	[Parameter()]
	[ValidateSet("CloudFlare","Google","Quad9")]
	[String]$Provider = "CloudFlare"
 )

	Foreach ($domain in $domains) {
	
		switch ($Provider) {
			"CloudFlare" {$url = 'https://cloudflare-dns.com/dns-query?name='+$domain+'&type='+$type; break}
			"Google"     {$url = 'https://dns.google.com/resolve?name=' + $domain + '&type='+$type; break}
			"Quad9"      {$url = 'https://dns.quad9.net:5053/dns-query?name=' + $domain; break}
		}
	
	
	
		$header = @{"accept"="application/dns-json"}
		$response = (Invoke-WebRequest -Uri $url -Headers $header -UseBasicParsing)
	
		if ($response.Content.GetType().name -eq "Byte[]") {
			$json = [System.Text.Encoding]::UTF8.GetString($response.Content)
		}
		Else {
			$json = $response.Content
		}
	
		$content = $json | ConvertFrom-Json
		$content.Answer
	}
}
