while you search for better job you can use something like this 😉
$leases = Get-DhcpServerv4Lease -ScopeId $scopeid -ComputerName $dhcpserver
foreach ($lease in $leases) {
$hostname = $lease.HostName
$ipAddress = $lease.IPAddress
$dnsHostNameEntry = [System.Net.Dns]::Resolve($ipaddress)
$dnsHostAddressEntry = [System.Net.Dns]::Resolve($ipaddress)
# here you should test for emtiness in $dnsHostNameEntry, $dnsHostAddressEntry - its your homework
if (($hostname -ne $dnshostnameentry.hostname)) -or ($dnsHostAddressEntry.AddressList.Count -gt 1) -or ( $ipAddress -notin $dnsHostAddressEntry.AddressList ) {
Big Alert !!!
}
}
you should repeat it (with appropriate code corrections of course) for forward and reverse scopes
