</div>Not sure exactly what you want to look at but we have a BSD-licensed delegation checking tool called DNSCheck that you could either take parts of or just try out straight off (<a href="https://github.com/dotse/dnscheck" target="_blank">https://github.com/dotse/dnscheck</a><span onmouseout="cancel = false; window.setTimeout(WRCHideContent, 1000); clearTimeout(showTimer);" onmouseover=" var self = this; showTimer = window.setTimeout(function(){WRCShowContent({'rating':{'value':94,'weight':63},'flags':{'it':1},'single':false,'ttl':3600,'expireTime':'20110916110546'}, self.className)},600);" class="wrc12" style="padding-right: 16px; width: 16px; height: 16px;"></span>). We also host an instance of this that you can try out without installing anything at (<a href="http://dnscheck.iis.se" target="_blank">http://dnscheck.iis.se</a><span onmouseout="cancel = false; window.setTimeout(WRCHideContent, 1000); clearTimeout(showTimer);" onmouseover=" var self = this; showTimer = window.setTimeout(function(){WRCShowContent({'rating':{'value':100,'weight':12},'flags':{},'single':false,'ttl':3600,'expireTime':'20110916113806'}, self.className)},600);" class="wrc11" style="padding-right: 16px; width: 16px; height: 16px;"></span>); but it does sound as if you might want to just grab a few of the modules from our Github repository...<br>
<br>
DNSCheck handles both dnssec and IPv6 and the policy for errors itself is very easy to change to suit your needs, if you dont want the default quite "strict" dns-standard ones.<br>
