example foo.com where www.foo.com uses a different IP

==========================================================================
$TTL     43200
 
@        IN    SOA    ns.foo.com.  webmaster.foo.com. (
                        2000122601 ; serial
                        10800      ; refresh
                        3600       ; retry
                        3600000    ; expire
                        86400      ; default_ttl
                      )
 
@        IN    NS     ns.foo.com.
@        IN    MX 5   mail.foo.com.
 
                               ; reachable services
@        IN    A      123.234.123.4
 
www      IN    A      234.123.234.6

                               ; aliases
ns       IN    CNAME  foo.com.
mail     IN    CNAME  foo.com.
=========================================================================

The '@' is not really necessary as long as the previous record was
foo.com.  This would be the zone file on ns.foo.com.

There seems to be a trend to use domain.com as the home page instead of
www.domain.com lately.  Anyone know of any reason behind this or is it
just an idea someone had?
