If named.conf is correctly set up with the domain name - then
you could use
$TTL 3600
@ IN SOA ...the SOA info
IN NS Nameserver record lines
IN A 1.1.1.1
www IN A 1.1.1.1
Last line can be converted to a CNAME...
www IN CNAME domain.com.
When you include IPv6 addresses into the mix...
using a CNAME saves you entering the same IPv6 address twice - so then
there really is a saving - especially when you include other alternative
labels like 'mail', 'pop', 'smtp', 'ftp' - etc - do them all as CNAMES!
$TTL 3600
@ IN SOA ...the SOA info
IN NS Nameserver record lines
IN A 1.1.1.1
IN AAAA 2001:1:1::80
www IN CNAME domain.com
What I think is your real problem....
Regardless of whatever which way you decide - apache will be given the
original name - DNS will not re-write that.. so you have to spell out
both names in your apache configuration files...
So (playing with virtual hosts)
NameVirtualHost 1.1.1.1
<VirtualHost 1.1.1.1>
ServerName domain.com
ServerAlias www.domain.com
...
</VirtualHost>
-and later for IPv6 - duplicate the above...
(this line next to the other "NameVirtualHost"
NameVirtualHost [2001:1:1::80]
<VirtualHost [2001:1:1::80]>
ServerName domain.com
ServerAlias www.domain.com
...
</VirtualHost>
