How to update DNS record

[Andi Clemens]

Hi,

I want to update our DNS servers periodically with some IP addresses. But I
don't know how to do this.
I searched the Internet quite a while but I haven't found a good example how
to do this.
I want to change the A-Record for some IPs, this shouldn't be too hard.
I looked at dnspython and twisted, but I really don't have a clue how to do
this.
Has anyone done this before?
