1. What is the reason to expect the name "ns1.apache.org" to have any
DNS records?
2. Using "all" as the final RRTYPE argument (or any other word beginning
with 'a' except "any") is interpreted by 'dig' as a request for an A
record. If you think it does something else, look closely at the
"QUESTION SECTION" of the output.
