Infrastructure addresses definition

Thu Feb 24 16:13:13 UTC 2011

How do you define infrastructure addresses in your network?
Ok, probably router loopbacks are some of them. Router LANs also.

But what about addresses used on WAN (or LAN p2p) links that are used 
for interconnections with customers?
What about addresses used for public servers (dns, mail, web, etc)?

Do you consider these as infrastructure addresses?
If yes, how do you define your iACLs with these included?
