Its even easier than that.  Don't mess with the .list files just change  the file

/etc/apt/apt.conf.d/000apt-cacher-ng-proxy

according to the login.

The contents of that file is just the address/port of the apt-cacher-ng server.

Acquire::http::Proxy "http://172.16.0.1:3142/";;

Just write a script to check what network you are on.  Like ping the
apt-cacher-ng server(s) until a response is sent and set 
/etc/apt/apt.conf.d/000apt-cacher-ng-proxy accordingly.

Try the following line with your own existing and non existing ips.

for f in 172.16.0.1 172.16.0.2 172.16.0.33; do if ping -c3 $f; then echo $f
yes;else echo $f no;fi; done
