Daily reverse DNS test problem
« on: November 20, 2011, 03:31:44 PM »

I can successfully pass every other test, except the one using dig -x. This is the output I'm getting:

Code: [Select]
; <<>> DiG 9.3.2 <<>> -x 2001:4860:800f::93

But the test fails due to a record mismatch. Is this something I'm doing wrong, or a problem on the other end? Thanks.

Not certain, I just pasted the following and it worked without issue:

Code: [Select]
; <<>> DiG 9.4.2-P2.1 <<>> -x 2001:4860:800f::93

Looking at how both of ours are formatted, it looks like you have line-breaks after "PT" and "86400". Try making those whole complete lines.
