Configuring BIND on dynamic IP??

Hello to all,my request here is directed to everyone with experience on network administration and in particular to somebody with enough skill on BIND.

Foreword:

My network is very strange,or at least atipical and,briefly speaking,structured as follows...

I have a registered hostname which is ik5bcu.cjb.net with CNAME linux.ik5bcu.ampr.org:

[marco@linux marco]$ dig linux.ik5bcu.ampr.org

; <<>> DiG 9.2.2-P1 <<>> linux.ik5bcu.ampr.org
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 61183 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 2

;; QUESTION SECTION:
;linux.ik5bcu.ampr.org. IN A

;; ANSWER SECTION:

linux.ik5bcu.ampr.org.  169916  IN      CNAME   ik5bcu.cjb.net.
ik5bcu.cjb.net.         60      IN      A       212.141.182.207

I use a dynamic DNS service offered by www.cjb.net so my IP address changes every time I issue a new dial-up connection.

What I would like to know is if can I have any chances to configure BIND so that it works as DNS for my network;I don't pretend to have a public and performing DNS server,but a functional DNS expecially to serve the requirements of my SMTP server:QMAIL.

I have installed the latest release:bind-9.2.2-23 along with caching-nameserver.

This last (caching),tested just yesterday,already gave me proof of very good performer for its speed in comparison to my old /etc/hosts /etc/resolv.conf only system.

Thanks for reading.

Regards,Marco
