We are implementing an enterprise distributed system with many Centos

dynamically.  We do have DHCP and use Dynamic DNS updates.


FWIW I would ask yourself if DNS is even the right choice. If you control the things doing the discovery and advertisement there are other (IMO better) alternatives. I like etcd personally, but there's a jillion key-value stores with service discovery built on top. Google for it.

I have been researching to see what 's out there or what's the common
practice. Though this is a pretty common but so far I haven't turned
up any promising leads. I did find Avahi but not sure if this is one.

Common practice for intra-server service discovery is not to use DNS, AFAICT.


Any one has any suggestions?

Well... maybe ask on an appropriate forum. This isn't a bind-specific set of questions.

Stack overflow or similar may be a better place to start.
