multiple ints: views or separate records?

As far as influence it seems you could restrict the connections on virtual IPs to specific subnets so that they don’t have a choice.  This can be done via ACLs in the views and/or via firewall rules (e.g. in iptables if this were a Linux host).

Subject: multiple ints: views or separate records?


I have a few systems with multiple physical and virtual interfaces. One system has a single A record but im considering splitting it up. I'd like to persuade users to talk with a specific interface depending mostly on the app and sometimes from the subnet where their request originates. I want to keep things really easy for the users. What's your experience in influencing that decision while keeping things dead simple? keeping in mind that they have the potential of communicating with the system from a number of different angles.

Is using views my best approach? Or would it be recommended to just settle and publish a bunch of CNAMEs (or A) and having them stick to using those? Or maintain both? Said another way, how well have your users adapted to name changes?
