PowerShell loop for DNS name lookup until resolved.

resolveDomain.ps1

while(1 -eq 1) {
  #get the IP of the domain assigned, by using the Cloudflare DNS server or replace with any other
  $ip = Resolve-DnsName -Name <domain_name_here e.g. www.github.com> -Server 1.1.1.1 -Type A -ErrorAction SilentlyContinue -ErrorVariable procErr
  
  #if there was an error then print a warning message
  if($procErr){
    Write-Warning "Not resolved!"
  }
  
  #if the IP is not null, means it was resolved successfully
  if($ip -ne $null){ 
    #get the date and time that the resolution started working on
    break #exit the loop and show the result
    Write-Host "Worked on: " (Get-Date) "(IP:" $ip.Address ")" 
  }
  #it seem the resolve did not happen, wait for 5 minutes and check again
  Start-Sleep -s 300 
}
