Hello.

I have a functioning DHCP/DNS (ISC Bind 9.6, DHCP 3.1.1) server running on Debian that I would like to add DynamicDNS functionality to. I have a pretty simple question: Does DynamicDNS require (or recommend) separate sub-domains? I have seen a few tutorials where the the clients that are acquiring their IP addresses and other networking information via DHCP are on a different sub-domain as the servers which are statically configured (both in terms of IP, and DNS). For example: All the clients are on ws.example.org and the servers on example.org.

Right now all of our servers and clients are in the same domain (example.org) but spread across different zone files (because we have multiple subnets). The clients are configured with DHCP and the servers are configured statically. If I want to setup DynamicDNS for the clients should I use a separate sub-domain? What's the best practice here (and why or why not would it be a bad idea to do otherwise)?

Thanks.
