Hi Raj,

Please try the script below on DNS server:

$ips="ip1","ip2"
 foreach($ip in $ips){
 $fqdn = [System.Net.Dns]::GetHostbyAddress($ip)|select -ExpandProperty hostname #get fqdn from ip
 $new=$fqdn+"."
 Get-DnsServerResourceRecord -ZoneName "yourzonename" -RRType cname|where{($_.recorddata).hostNameAlias -eq $new}
}

Best Regards,

Anna Wang
