Can someone replicate this: I have a fully working @domain.com without issues. I created a sub domain A record called 'report' (so report.domain.com) that points to a different ip address. This works perfectly fine. I then created another sub domain A record called 'reporttest' (so reporttest.domain.com ) and it DOESN'T work. I created test.domain.com and that works just fine. This is on a perfect debian lenny server with ispc 220.127.116.11 . I can report the bug but want to see if someone else can verify first.
