Hi karunakar, You can verify the DNS device path with HTTP boot feature. After the successful HTTP boot DNS parsing, the device path should be like: //....../Mac(...)[/Vlan(...)][/Wi-Fi(...)]/IPv4(...)[/Dns(...)]/Uri(...).
That is recommend way for the verification. Besides, you can also draft the App to call the DevPathFromTextDns and DevPathToTextDns libraries for the more verification.
