It varies with bind version you are using.
Bind8 has a dynamic zone update feature in which you can specificy arbitrary
bind8 name servers that are updated dynamically when a master zone file is
modified on the master server. It will propogate the changes out to all slave
servers inside it's update records. You can arbitrarily set which servers are
to be updated, so this is probably the feature you want to use.
You will have to setup records with update(master) allow_update(slave)
features to achieve this. With bind8, you can set these in the local zone
configuration per domain, or you can do a server wide setting to update all
domains by default.
Just a note, cable modems aren't going to always have a static IP. Rogers is
doing that because they are having lots of troubles with their DHCP servers.
Hope this helps. Consult the manpage for named.conf for futher information.
