I used the tool and checked the list of domains and found that some domains were no longer in use. Hope Dev also remove it from the list of domains please!

is providing DOH

Looks like The Great Wall DoH is no longer updated, I have asked BBCan77 if he can switch to your list as it seems to be maintined. This would be for DNSBL and IP Blocking.

Thanks for the list, I have compiled this list to adblock syntax.

doh.dns.apple.com.v.aaplimg.com
doh.dns.apple.com
noticed these 2 getting hit

You have added mask.icloud.com and mask-h2.icloud.com to the list.
These domains should not be blocked, because the domains are used to allow network providers to control icloud private relay usage. According to this and this document, the DNS query reply needs to be NWDOMAIN. If the acces is simply blocked, there will be delays.

The following DoH servers can be added to the list:

https://doh.post-factum.tk/dns-query
https://dns.njal.la/dns-query
https://doh.this.web.id/dns-query
https://dns.therifleman.name/dns-query
https://dns1.ryan-palmer.com/dns-query
https://doh.bortzmeyer.fr/
https://query.hdns.io/dns-query
https://opennic.i2pd.xyz/dns-query

Unfortunately both IPs below in use for CDN for Cloudflare. Blocking HTTPS to these IPs will break anything hosted by these IP addresses(hosted js files for wordpress theme). Please update.

Hi, I need a v6-enabled version of these lists. I'll be making one shortly, and wanted to ask what implementation is preferable for you to pull back into your repository.

I currently only use the list.txt file, and my use case doesn't care if the complete list is in 1 or multiple files, so I don't have strong preference for any of the possible implementations:

• separate list-v6.txt with v6 addresses, hosts in the same order as in list.txt
• append the v6 list to list.txt at the end of the file
• for every line with v4 mapping in list.txt, insert a line with v6 mapping immediately after it

The same question and implementation options apply to iplist.txt, as I see it.

Cheers

Firefox has added NextDNS as a DoH provider by default. I couldn't find anything in the list mentioning them. Are they there and I missed it, or could they be added?

#19 here: https://developer.apple.com/support/prepare-your-network-for-icloud-private-relay

mask.icloud.com
mask-h2.icloud.com

I don’t think they are used for any purpose other than DNS.

I was trying to add all ControlD Free DNS offerings to the list, however I've noticed they offered more variety than before.
https://controld.com/free-dns?
Beside the regular ones, they have some No "xxx" (Ads / Adult / Dating / Gambling) etc and all can be freely combined.
By stats, It potentially contain 511 (9+36+84+126+126+84+36+9+1) varieties of DoT hostnames (all under *.freedns.controld.com)...

I have no clue if all these should be listed under this, since it's DoH Servers (but there are DoT lists) or even how to add them all...
