This is a bug. I requested ONLY A records and as seen by the -v output, it does an A, AAAA, and MX record lookup (the default if no -t is specified). Trying other -t options: $ host -t cname www.air-watch.net www.air-watch.net is an alias for air-watch.net. $ host -t mx www.air-watch.net www.air-watch.net is an alias for air-watch.net. air-watch.net mail is handled by 900 mxr01.hvn01.dsl.net. air-watch.net mail is handled by 900 mxr01.nyc01.dsl.net. air-watch.net mail is handled by 10 mail.gti-host.net. $ host -t aaaa www.air-watch.net www.air-watch.net is an alias for air-watch.net. work as expected. Interestingly, dig performs the query correctly, but then its default is to perform an A record lookup only anyway. This also occurs if the name to lookup is not a CNAME: $ host -t a air-watch.net air-watch.net has address 66.95.77.17 air-watch.net mail is handled by 900 mxr01.hvn01.dsl.net. air-watch.net mail is handled by 900 mxr01.nyc01.dsl.net. air-watch.net mail is handled by 10 mail.gti-host.net. Version-Release number of selected component (if applicable): bind-utils-9.3.1-8.FC4 How reproducible: Always Steps to Reproduce: 1. host -v -t a HOST Actual Results: host performs a query for A, AAAA, and MX records. Expected Results: host performs a query for A records only. Additional info:
Yes, this does appear to be a bug. Will fix in next version (bind-9.3.1-11+).
This is now fixed with bind-9.3.1-10_FC4 (FC-4) & bind-9.3.1-11 (Rawhide), which should be in tomorrow's FC-4 updates + Rawhide release. ISC Bug #15287 was raised on this issue, which will hopefully be fixed in future upstream bind releases.
Where does ISC keep their list of bug reports? I could never find a public listing, just an email to submit to.
Actually, ISC bug #13230 had already been raised on this issue - it is listed at: http://www.isc.org/index.pl?/sw/bind/bind9.3.php This issue has been fixed with bind-9.3.1-10_FC4, which is now being pushed to FC4 updates.
Thanks for the bug report. This particular bug was fixed and a update package was published for download. Please feel free to report any further bugs you find.
