Description Guy Martin (RETIRED) gentoo-dev

dig and host want to resolve in a nibble format with .ip6.arpa (which is incorrect) instead of .ip6.int even if you don't specify -n.

bind-tools 9.2.2 is unafected by this bug.
the following behaviours are reproducibles on all my box :

Correct behaviour (v 9.2.2) :

Sorry, this is not correct. Bitstring has been moved back to experimental in RFC 3363 Chapter 3 and is not used anymore (in fact, it has never been delegated at all). 

The current way to go is nibble format in ip6.arpa which is exactly the thing bind-tools 9.2.3 is doing

Ok then it's a problem of documentation.

The man page of host and dig does not document the -i options which is the right to use (and I just discovered :)

Those commands works :

# dig -i -x 2001:6f8:204:20::1

Comment 3 Bernhard Schmidt 2004-04-13 11:44:28 UTC

Move/copy your delegation to ip6.arpa and you'll need no additional switch, Easynet can surely do that :-)

I just did :)

Comment 5 Jonathan Stewart 2004-06-04 14:20:54 UTC

can this bug be as resolved then?

Seems like it's more a bug with Bind for not documenting the behavior than with gentoo.

Confirmed as documentation job for BIND than for Gentoo.

Thanks!
