dns record with an '@' as the host name

[Daniel A. Monjar]

I was looking at the DNS setup for a friend's domain and noticed this:

----
> ls pilanet.com
[NS3.WEB.BELLSOUTH.NET]
$ORIGIN pilanet.com.
@			4D IN A		209.238.131.108
smtp			4D IN A		209.238.131.108
www			4D IN A		209.238.131.108
>
----

I've never seen a host of '@' before.

Is it the standard shorthand for, in this case, 'pilanet.com'?  Does
'nslookup ls' just dump out the configuration records?
