I think that is a porn site.  If you mean to use that name as an 
example, please use "example.com" instead.  Putting HTTP links to 
pornography in your emails is a sure way to fall afoul of various 
content filtering solutions which are in common use.

See RFC 2606 regarding reserved domain names like "example.com".

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

This zone file would fail named-checkzone(8) testing if loaded as 
"xxx.com", because there is no "A" record for the NS name, 
"ns1.xxx.com."  This zone would fail to load.

If any of your NS names are inside the zone, you must have either or 
both A and AAAA records for those NS names.  Here is the same zone 
without the XXX and with all relative names:
