Since the new range of IPs are routed from your ISP to your PIX, I assume
you want to map the new external IPs to an internal/DMZ servers within your
network.

1. Created STATIC NAT (one-to-one mapping), let say the server is on the dmz
and your range is 1.1.1.1/29 and your DMZ server is 192.168.50.12

    static (dmz, outside) 1.1.1.2 192.168.50.12 netmask 255.255.255.255

2. Created an access-list if you don't have one for the external interface
to allow the traffic to this DMZ server, let say the server is hosting a
shoutcast server on port 8000

     access-list outside_in permit tcp any host 1.1.1.2 eq 8000

3. Bind the access-list outside_in to the outside interface

    access-group outside_in in interface outside

The PIX should automatically ARP for the new IPs.
