Hi all,
Is there a way to get DNS dynamic A records for only servers with Windows AD integrated Zone, not including workstations?
Thank you!

2022-04-07T01:52:55.533+00:00 The safest way is to not to mingle IP address ranges of static and DHCP created records. Then you only need to check the IP address to know if it's been created/updated by DHCP.
I think a problem you may have is if you've allowed the machines with statically assigned IP addresses to register themselves or update their resource records in DNS. I believe that may add a timestamp value to the resource record. But if that isn't happening then the presence of a timestamp value (or one with a date of 1/1/1601) should identify a "static" record.

$OldObj = Get-DnsServerResourceRecord -Name "Host01" -ZoneName "contoso.com" -RRType "A"
$NewObj = $OldObj.Clone()
$NewObj.TimeToLive = [System.TimeSpan]::FromHours(2)
Set-DnsServerResourceRecord -NewInputObject $NewObj -OldInputObject $OldObj -ZoneName "contoso.com" -PassThruHostName RecordType Timestamp TimeToLive RecordData
-------- ---------- --------- ---------- ----------
Host01 A 0 02:00:00 2.2.2.2if passthrough is missing, from Set-DnsServerResourceRecord,, what will happen? thank you!

2022-04-15T18:48:48.02+00:00 The help for the cmdlet -PassThru parameter is pretty clear:
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.In your case, you wouldn't see this in the output of the script:
HostName RecordType Timestamp TimeToLive RecordData
Host01 A 0 02:00:00 2.2.2.2EDIT: Changed "would" to "wouldN'T".
