Configuring Bind on a dynamic ip, DDNS.

[Eduardo Bonsi]

Hello all. I had to cancel my static external ip because my ISP wants 
too much money for it and it did not justify to pay for that kind of 
price since we are a small firm. I tried to negotiate but we all know 
how hard is to convince a corporate monopoly executive to get down from 
the clouds to reality.

So, I have my server configured and working fine internally using BIND 
and I have OpenDNS also working and updating the dynamic ip changes from 
my ISP. My questions are: -How do I go about configuring the domain 
using bind to catch the external dynamic ip given from my ISP both on my 
DNS Server and at the parent?

Right now I have my external ip temporarily configured as 0.0.0.0
This external dynamic ip pass through the router and gives resolution to 
access the internet.
What I need is to make the 0.0.0.0 = external dynamic ip given from my 
ISP to fit to 0.0.0.0 whatever it update at OpenDNS. Then make whatever 
dynamic ip = to my domain.

Is there a way to configure that using BIND?
Has anyone here done that successfully could give some insides on the 
configuration?

Thanks!
