I saw today that one of the biggest adlist providers - hagezi will stop providing the "hosts" format which mikrotik adlist feature uses. The main concern is they want only to optimize their lists for size and efficiency.
As i looked into AdGuard format converting blindly will not work, because this format blocks domain and all subdomains listed in each record. For example:
||example.org^
Will block:
http://subdomain.example.org/ad1.gif
It will not block:
http://ads.example.org.us/ad1.gif
http://example.com/redirect/http://ads.example.org/
I guess if they want to block only specific subdomains they will do the below:
||subdomain.example.org^
I compared two versions of the hagezi pro lists - one with mikrotik (hosts) format and one with adguard(wildcard) format. Normal one was 300k and adguard one was 170k records.
Will it be possible mikrotik to support this format or the format that for example is most popular with pihole, so we can use most of the lists.
