"dig PTR for more points" not working?
« on: April 18, 2009, 10:36:26 AM »

Doesn't seem to like anything I submit. For example, here's the reseult from ipv6.he.net's address, which reverses just fine and which I had not submitted before. If anything should work, it should be this!

Summary of user's dig query
IPv6 Address: 2001:470:0:64::2
Status: NOERROR
Reverse ip6.arpa:
0.7.4.0.1.0.0.2.ip6.arpa.

Validating user's dig query
Result: Fail

1) email ipv6@he.net (I really cannot stress this enough) when you have problems. It opens "trouble tickets" for us to look at faster than glancing at the forums.

2) include the exact data you are trying to paste so we can test with.

I think I found it...

The answer section is not displayed properly when there is a tab between the lifetime and the 'IN' keyword, which apparently most servers or admins put there (I've found a few hosts that did work.) If the terminal is set to the standard 80-column width, this tab is not displayed and parsing of the output fails:

;; ANSWER SECTION:
2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.6.7.0.0.0.0.0.0.0.7.4.0.1.0.0.2.ip6.arpa. 86328IN PTR he.net.

81 columns:
