Hi Stace.
The transport protocol used to ask the question is (or should be)
independent of the question being asked. So in this case asking for a
PTR record for an IPv6 address wouldn't change whether IPv4 or IPv6 is
used to make the recursive queries.
I've done a bit more testing on this, and it seems like if you use the
+ns option, delv ignores the -4, -6 and -b options. I'm not sure if that
is by design or not, but it would be useful to be able to control which
source IP address delv uses for queries and whether delv queries for A
or AAAA records? (It would also be good if it queried for both by
default -- i.e. if neither -4 or -6 were specified?)
Can anyone advise whether this something I should raise a bug report for?
Nick.
P.S. Using +ns also causes delv to ignore a server specified with the @
option, and in this case it logs a message like: ";; WARNING: using
internal name server mode: '@8.8.8.8' will be ignored"

But I also noticed that delv only makes A queries (not AAAA), and even if I specify
"-6" on the command-line it makes no difference?
Have yo tried using an IPv6 address with the -x option?
delv -x ::ffff:45.90.5.195 +ns +qmin +maxqueries=100
