IntoDNS has no IPv6 support (and therefore produces spurious errors on IPv6-only nameservers). It sends errors when there is no "www" name in the zone which is quite stupid. It can not test TLD (it says "Invalid request!) May 13, 2009 at 6:46

There are several. I recommend Zonecheck, which is also available as free software that you can install on your own machine.

DNScheck is nice, too, and the only tool able to check DNSSEC.
I wrote a paper listing and comparing many online tools.

1checkdns sends a spurious (and quite stupid, IMHO) warning when you have only one MX server. It seems to indicate a lack of knowledge regarding the way email works. May 13, 2009 at 6:55
You should definitely check out http://dnscog.com/report/serverfault.com
They give a nice detailed report and supply some recommendations too.
