Hello Eric Kom,

are you sure, you want this:

> ns1     IN      A       41.134.194.90
> ns2     IN      A       41.134.194.91
> ns1     IN      A       10.0.0.80
> ns2     IN      A       10.0.0.82

This results in a round-robing and I would not get in 50% of  all  cases
the right domain.

> www     IN      A       10.0.0.81
> www     IN      A       10.0.0.82
> mail    IN      A       10.0.0.84
> backup  IN      A       10.0.0.102

How can someone reach your Web- and Mail-Server, if you have setup  them
in a private network?

> ftp     IN      CNAME   www
> img     IN      CNAME   www
> *       IN      CNAME   www
> imap    IN      CNAME   mail
> pop     IN      CNAME   mail
> pop3    IN      CNAME   mail
> smtp    IN      CNAME   mail

Are you sure, this is working?  The "*" wildcard  will  even  catch  the
"imap", "pop", "pop3" and "smtp" hosts and redirect them to "www"

> 80              IN      PTR     ns1.metropolitanbuntu.co.za.
> 82              IN      PTR     ns2.metropolitanbuntu.co.za.
> 81              IN      PTR     www.metropolitanbuntu.co.za.
> 102             IN      PTR     backup.metropolitanbuntu.co.za.
> 108             IN      PTR     printer-server.metropolitanbuntu.co.za.
> 31              IN      PTR     ldap.metropolitanbuntu.co.za.

How should this work?  are the servers only accessibel  from  the  local
and private network?

Thanks, Greetings and nice Day/Evening
