i'm not exactly sure what you're referencing, so i'm going to say a bunch of nonsense that will hopefully clear things up. i'm not sure what you already know. the removal of subdomains that i suggested is an enhancement to reduce the number of duplicate entries in the blacklist; not an added feature. the current functionality, as far as i understand it, works like this: DL from each URL consolidate all the DLed lists into one blacklist list (aka $WORK1) remove (some) duplicates remove whitelisted entries create additional dnsmasq config file (aka /tmp/etc/dnsmasq.adblock) the dnsmasq config file that is created, is formatted as: Code: address=/domain.xxx/0.0.0.0 dnsmasq itself will block all subdomains of domain.xxx by design. i.e. it is not necessary to create: address=/sub1.domain.xxx/0.0.0.0 address=/ads.domain.xxx/0.0.0.0 address=/etc.domain.xxx/0.0.0.0 in my view, IF the black list contains domain.xxx, then all listed subdomains should be considered as a duplicate. in other words, the functional behavior of: this Code: address=/domain.xxx/0.0.0.0 address=/www.domain.xxx/0.0.0.0 address=/ads.domain.xxx/0.0.0.0 address=/etc.domain.xxx/0.0.0.0 and Code: address=/domain.xxx/0.0.0.0 is exactly the same. so why have a bloated list (#1), when we could have a more compact list (#2)? in your example of "block system.mondeos.pl but allow mondeos.pl", it depends how the list is structured. if the list is like: Code: 127.0.0.1 system.mondeos.pl then that's good. it will work as you want. it will still block system.mondeos.pl and *.system.mondeos.pl, but *.mondeos.pl is allowed (except system.mondeos.pl). sideNOTE: if you put mondeos.pl into the whitelist, then even system.mondeos.pl will be removed. if the list is like: Code: 127.0.0.1 mondeos.pl 127.0.0.1 system.mondeos.pl 127.0.0.1 ads.mondeos.pl 127.0.0.1 tracking.mondeos.pl then system.mondeos.pl will be blocked because of the line "mondeos.pl" anyway. following my suggestion of removing subdomains will remove system.mondeos.pl, ads.mondeos.pl, and tracking.mondeos.pl, but only because "mondeos.pl" is listed. if the list is like: Code: 127.0.0.1 system.mondeos.pl 127.0.0.1 ads.mondeos.pl 127.0.0.1 tracking.mondeos.pl then subdomains will not be removed. mondeos.pl is allowed, as well as *.mondeos.pl, except system, ads and tracking.
