[NTLUG:Discuss] Dynamic IP and External DNS - is it possible?

[Keller Giacomarro]

This is something of a Linux question, since I'm implementing it in Linux -
please let me know if this type of query is inappropriate for this list.

Being the student of networking that I am, I've recently gotten very
interested in DNS.  To learn more, I'd like to set up an external DNS server
for my personal domain.  Here's what's setup now:

kellerg.com points to my RoadRunner cable IP address.  I'm using
no-ip.comto accomplish this.
Everytime my IP changes, no-ip updates its DNS A record for kellerg.com with
my current IP.

What I want to have happen is DNS requests for my domain should come to my
bind9 DNS server.  I know that I can just add CNAME and MX records with
No-IP, but I really just want no-ip to resolve kellerg.com and then pass
everything else to my nameserver.

No-IP says this isn't possible without a static IP.  Is that true?

Thanks in advance to the really smart DNS peoples. =)
