What is the simple and safe way to make onw dyn dns zone?

[Georgy Goshin]

Hi!

I'm porvide it support for my clients and most of them sitting behind 
dynamic ip. Is there a way to create one dynamic zone where all my clients 
will register their addresses in case if the addesses is changing. Some of 
that clients uses Linux (LRP) routers, some uses linux based mikrotik 
routers and some of them - simple windows clients. What is best way to 
realize this?


Thanks,
G.
