I have to ask... Why did you call the file "allow-ip-addresses" when
you are using domain names? Personally, I'd call this file
"allowed-domains" and set up another ACL:

acl allowed-CONNECT-IP dst "/squid/etc/allow-ip-addresses"

In that file you can specify IP addresses, IP addresses with netmask or
use CIDR notation.

Of course having two ACLs would require re-working the http_access rules
you have here. Something like:

http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow CONNECT allowed-CONNECT
http_access allow CONNECT allowed-CONNECT-IP
http_access deny CONNECT
