You may get the information from AD itself.. Does that work for you?
Get-ADComputer -Filter 'Name -like "NYC*"' -Properties IPv4Address | Select Name,DNSHostName,IPv4Address,`
	@{N="Ping Status";E={If(Test-Connection $_.DNSHostName -EA Silentlycontinue -Count 1){"Pinging"}Else{"Not Pinging"}}} |
	Export-Csv C:\report.csv -NTI

Thanks for your response, Subsun.  Will this extract machines from the 172.20.30.x network only?  I have other networks but do not want to export that info.  Thanks.

Nope.. I missed that part.. :-) .. It is possible to add filter to above code however it will be an overhead..

You can use DnsShell (It's a free module)
Get-DnsRecord -RecordType A | ?{$_.Name -like "NYC*" -and $_.RecordData -like "172.20.3.*"} | Select Name,RecordData | Export-Csv C:\report.csv -NTI

Thanks Sunsun!  I got this to work, but needed to add the -zone and -server parameters.  I also removed -NTI as I was getting an error from it for some reason.  Appreciate all the help!  

Get-DnsRecord -zone "" -server "DNShostname" -RecordType A | ?{$_.Name -like "NYC*" -and $_.RecordData -like "192.168.*.*"} | Select RecordData,Name | export-csv "C:\Temp\DNS Script\report.csv"
