dynamic dns update

[David Byron]

Hoping someone else has put the pieces together for this....

I'd like to send a dynamic DNS update with the results of a dhcp client
query from my embedded target running busybox/uclibc.

> 4) DNS server stores and offers to clients the new A and PTR record:
>    "client-12-31.dynamic.abccheese.com IN A 192.168.1.33"
> 
> This can be done in an RFC-compliant manner.

Anyone know how to do #3 so that my DNS server will do #4?

Thanks much for your help.
