I have a simple IP address design question.
When I design internal networks, I create /24 networks for all my internal VLANs
For example:
Servers are 10.1.10.0/24
Clients are 10.1.11.0/24
Management is 10.1.12.0/24
etc...
All these networks summarize nicely into a /16.
I would then address my DMZ in a different class network like 172.16.1.0/24.
Is there any reason why I shouldnt use a network that fits in my 10.1.0.0 /16 summarization? For example 10.1.200.0/24. All DMZ and internal networks will all be on separate physical interfaces and secured with ACLs, IPS, etc.
I'm just trying to clean up routing tables and lessen the administration when creating new DMZs.
