<div dir="ltr">Yeah, you need to walk up the root tree to fetch the NS (and especially glue), as using anything else you may not spot issues as the NS records coming back from your actual servers can overwrite what was initially learnt from the root servers in cache if the timing (re TTL) is *just* right.. I've seen quite a few weirdnesses where you lookup NS from the root servers, and query one of those NS's (NSii? lol) and get a different set of NS records come back.<div>
<br></div><div>It'd be really handy in your output if you make it really obvious if you're getting different records back from any of the DNS servers. (Maybe you are, but would be cool if you can, if you're not :) )</div>

Looks good, my only comment would be it's best to collect the ns records from the root servers rather than Google's public dns servers.<br>
<br>
While functional it's probably not the best way to go...<br>

<div class="HOEnZb"><div class="h5">Hi All,<br>
<br>
I hope/think this is okay to post here.<br>
<br>
I’ve been using <a href="http://intodns.com" target="_blank">http://intodns.com</a> for a long time now (and previously dnsreport) and it is a great tool for checking DNS issues.<br>
<br>
Recently I have started working on my own as intodns doesn’t always display the information that I want.<br>
<br>
I would love to get some feedback and suggestions.<br>
<br>
Here is the current link:<br>
<a href="https://portal.dalegroup.net/dn42/dns.php" target="_blank">https://portal.dalegroup.net/dn42/dns.php</a><br>
<br>
I don’t expect it to be a replacement for <a href="http://intodns.com" target="_blank">intodns.com</a> (at least not yet!), but it does do things a bit differently that may be useful.<br>
<br>
Thanks!<br>
<br>
P.S no idea if the site will crash as it is very new code :D<br>
