Sound function check vs Digger DNS lookup

You can see demos related to sound when developing iPhone apps.

Digger is a DNS lookup tool for iPhone. Enter a name, pick a record type, and inspect the full current Result—without uploading your queries. It talks DNS directly. It does not run the dig command. Switch between a structured view and generated dig-style text, then copy or share the view you are looking at. Query A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV, CAA, HTTPS, and SVCB. Use the system resolver or a custom server. Choose automatic, UDP, or TCP. EDNS is on by default; the DO bit is optional. Cancel a Query in flight. Results include the response code, flags, all four sections, timing, and wire size. NXDOMAIN and SERVFAIL are DNS Results, not crashes. Digger does not validate DNSSEC. Privacy: Query data is not uploaded. Results are discarded when you leave them. Recent Queries stay on this device as name + type only. Clear History anytime in Settings. Digger is not a VPN or device-wide DNS changer. No DoH, DoT, or zone transfers.
