OK, I've done my research on DDSN. But everything I read about DDNS indicates its only purpose it to let folks on the internet get to your home website (or other IP server) using a hostname, even if your IP address is assigned and renewed using DHCP (i.e. you do not have a static IP address).
You are referring to what is well-known as DynDNS. It is a publicly available DDNS server for your home machine, and the update is initiated with a custom application using a custom protocol (not TSIG based to my knowledge).
I thought maybe DDNS is also a more generic feature of DNS servers. I looked through the BIND9 README and FAQ. I do see the mention of dynamic updates, an "allow-updates" parm and something called TSIG. Is that the feature I want?
Exactly. Unfortunately I cannot point to much more information either. But it's not so complicated. The needed information to set up the TSIG key and server configuration is in the man pages, and it should be easy going with the HOWTO I mentioned before. The best resource about DHCP in general (and probably also about dynamical DNS) is the DHCP book from Ted Lemon and Ralph Droms. Peter
