There are certain situations where you would want to setup yourown hostlist. since the xolox host list is encoded and not just plain text like most other clients, you have to manualy encode the ip numbers. That can take a very long time if you are trying to code 500 ip numbers.

I did end up making a program to code them, but it was in yabasic, so its not really for distribution. If his program works, then you should be able to put in a list of ip numbers and it will output a list of encoded ip numbers.

Could be very helpful, if you cannot connect to the network try adding a bunch of host caches to your cache list (encoded of course)
