Netdestination of allowed hosts

Hey guys,

I want to know if somebody out there is using a netdestination which has more than 50 hosts on a high density network. I'm asking this because we want to deny access to a 16bit network but we want to allow access for some hosts on that network. We thought on adding an allowed hosts alias in order to add new hosts easily in the case we don't know they exist in whole 16bit network.

So our rules might look like this:

ip access-list session internal-access-acl
any any svc-dhcp permit
user alias local-dns svc-dns permit
user alias internet any permit
user alias allowed-hosts any permit
any any any deny
!


Do that might impact network performance?

Thanks in advanced

Even if we will have more than 300 thousand hosts in that destination?

Under

Under what circumstance would you have to track 300,000 hosts? You might have to redesign your network, in that instance.
