I think the issue is that the solution you're suggesting is a misplaced hack to something that isn't broken. As has been stated previously by many others, the solution to this problem is NOT to hack the resolver (this is not the location of the problem), but to have the domain administrator fix the problem with their broken DNS. I agree with Jordan's response. Present these changes to Paul Vixie. If you can convince him that this is desired and needed functionality (I'm not convinced that it is), then it might be worth discussing. Something tells me that there is a reason this has not been implemented before (this doesn't seem to be a new idea). -- Christopher Nielsen Scient: The eBusiness Systems Innovator <http://www.scient.com>; cnielsen@scient.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
