Hello,
1.1.1.1 is returning a timeout when looking up a SOA record for ‘office.de’. It appears to be doing this because the A record that the SoA points to doesn’t exist. My expectation would be for 1.1.1.1 to return the information about the SoA similar to what 8.8.8.8 does.
Using Cloudflare
dig @1.1.1.1 SOA office.de

; (1 server found)
