Using a DynDNS hostname in master-statement for a bind slave?

Hello everyone,

sorry if this is a stupid question, I would love to get a RTFM
pointing me to the right documentation (I found none...).

My setup is like this (at least that is my plan):

In my home network I have:
Host A with bind as master for my zone example.org
Host B with bind as slave for my zone example.org, Host A set as its
master

The slave server (HOST B) is reachable from the internet via a dynDNS
hostname.

Now I want to setup another bind as slave on a server hosted at my
provider. It should use HOST B as its master, to transfer the zone and
act as a slave.

BUT I found nothing in the documentation on how to deal with a master
server that has no fixed IP and is reachable via a dynamic hostname.

Is this possible? Or do I have to setup a VPN to connect the external
server to the home network?

Thanks in advance for any tips or tricks or hints...

Regards,
Johannes
