If anyone's wondering which are the "High-risk TLDs" blocked in the "zero" filter: CF, CG, GA, GQ, ML, TK, TOP, WIN (right now, i guess it may change any time)

The "kids" filter blocks the same TLDs, so it allows XXX or PORN, i guess they just block individual 2nd level domains.

I just looped through IANA's TLD list with a simple script to get this. The resolver returns NXDOMAIN with "negative-caching.dns0.eu." SOA for the blocked ones:

    $ kdig +tls ns tk @zero.dns0.eu
    …
    ;; ->>HEADER<<- opcode: QUERY; status: NXDOMAIN; id: 39321
    …
    ;; QUESTION SECTION:
    ;; tk.                   IN NS

    ;; AUTHORITY SECTION:
    tk.                  300 IN SOA negative-caching.dns0.eu. hostmaster.tk. 0 1200 300 1209600 300



It seems pretty ridiculous to block those domains outright. There are plenty of legitimate government, tourist and local sites, which could at least be whitelisted.

They've blocked UNICEF's link shortener: https://uni.cf


"They've blocked UNICEF's link shortener: https://uni.cf"

Which I consider a good thing, why route links through the influence space of a country that is in a civil war with foreign mercenaries running parts of the show?


That's not their reason for blocking, since e.g. North Korea is allowed (tried airkoryo.com.kp).
