'bind' is the internet domain name server from ISC (www.isc.org/bind) 
and is by far the most ubiquitous nameserver out there and a rather 
important part of the fabric of the internet. You need bind version 8 or 
9 for this to work.

Anyway, here goes:

zone-file (e.g. bottles-of-beer.example.com)
--------------------------------------------
$TTL 86400
$ORIGIN bottles-of-beer.example.com.
	IN	NS	ns.example.com.
	IN	SOA	ns.example.com. postmaster.example.com. (
			1 ; Serial
			28800 ; Refresh

			600 ) ; Minimum
$GENERATE 2-99 $ CNAME ${-1}
1	IN	CNAME	no
