I think that is a porn site. If you mean to use that name as an<br>
example, please use "<a href="http://example.com" target="_blank">example.com</a>" instead. Putting HTTP links to<br>
pornography in your emails is a sure way to fall afoul of various<br>
content filtering solutions which are in common use.<br>
<br>
See RFC 2606 regarding reserved domain names like "<a href="http://example.com" target="_blank">example.com</a>".<br>

It's not unusual to point an "A" record for "@" at a HTTP server.<br>
Whatever you are not understanding here, I can't tell.<br>

This zone file would fail named-checkzone(8) testing if loaded as<br>
"<a href="http://xxx.com" target="_blank">xxx.com</a>", because there is no "A" record for the NS name,<br>
"<a href="http://ns1.xxx.com" target="_blank">ns1.xxx.com</a>." This zone would fail to load.<br>
<br>
If any of your NS names are inside the zone, you must have either or<br>
both A and AAAA records for those NS names. Here is the same zone<br>
without the XXX and with all relative names:<br>
