Report on Machines with DNS servers other than X, Y, or Z

[EvrazNA]

Would someone please help me write (or modify an existing) report that produces a list of machines with DNS servers that do not match a small list of "approved" DNS servers?

Desired Output:

ComputerName, IPLocation, DNS1, DNS2, DNSx ...

Thanks!

Modifying "Network: No DNS server specified": List machines where the DNS search list doesn't contain one or more of Cloudflare, Google, Quad9, OpenDNS (to use some actual examples):

Select Top 1000000
  tblAssets.AssetID,
  tblAssets.AssetName,
  tblAssets.Domain,
  tblAssets.Username,
  tblAssets.Userdomain,
  Coalesce(tsysOS.Image, tsysAssetTypes.AssetTypeIcon10) As icon,
  tblAssets.IPAddress,
  tblAssetCustom.Manufacturer,
  tblAssetCustom.Model,
  tsysOS.OSname As OS,
  tblAssets.SP,
  tblAssets.Lastseen,
  tblAssets.Lasttried,
  tblNetwork.DNSServerSearchOrder
From tblAssets
  Inner Join tblAssetCustom On tblAssets.AssetID = tblAssetCustom.AssetID
  Left Join tsysOS On tblAssets.OScode = tsysOS.OScode
  Inner Join tsysIPLocations On tsysIPLocations.LocationID = tblAssets.LocationID
  Inner Join tblState On tblState.State = tblAssetCustom.State
  Inner Join tsysAssetTypes On tsysAssetTypes.AssetType = tblAssets.Assettype
  Inner Join tblNetwork On tblAssets.AssetID = tblNetwork.AssetID
Where
 tblState.Statename = 'Active'
 And tblNetwork.IPAddress <> '0.0.0.0'
 And tblNetwork.IPAddress <> ''
 And tblNetwork.IPEnabled = 'True'
 And NOT (tblNetwork.DNSServerSearchOrder LIKE '%1.1.1.1%'
          OR tblNetwork.DNSServerSearchOrder LIKE '%8.8.8.8%'
          OR tblNetwork.DNSServerSearchOrder LIKE '%9.9.9.9%'
          OR tblNetwork.DNSServerSearchOrder LIKE '%208.67.222.222%'
         )
Order By

Thank you I stole part of this to report on DNS servers that are not our Corporate ones.
