Adding IP addresses to Cisco ASA 5505

We have 16 IP addresses currently pointing to our router to used for externally facing services. We have been assigned 8 more and I'd like to configure the router to accept these IP addresses.  Where can I do this in the ASA 5505?  I'd prefer to use the ADSM.

Also, our range of IP addresses are actually 2 sets or 8, is it tru that I can only use 6 from these 8 addresses and that the IP address at each end is unusable?

You can just use those additional addresses like the ones you already have, you do not need to specifically add them for the rest.
If you have two sets with a subnet mask of 255.255.255.248 the you can indeed only use six. The first address is always the network address of that range and the last one is the broadcast address for that range.
Hi,

There is two ways:

1. configure DMZ interface, and use the subnet on DMZ interface
2. make static nat for public to internal ip addresses, and ASA advertise the IP address with Proxy arp..
