Gemini解释：由于 CA/B 论坛的新规，某些情况下通配符证书不再支持 HTTP 验证，必须通过 DNS TXT 记录来证明你对该子域名的所有权。
Cloudflare Tunnel添加子域名时，会为该特定主机名申请一张“专用证书”。这种专用证书的优先级高于通配符证书。

We are honoured to be one of the first recipients of the Nominet DNS Fund, which recognises the importance of supporting the quiet work behind the scenes.
We thank @Nominet for their forward thinking - helping public interest nonprofits, such as Quad9, who work every day to maintain internet integrity, and the security and privacy of end users around the world.

Congratulations to the other recipients!
Alfis #DNS, I2P/level 1, and other centralized or CPU‑intensive non‑permanent domains are not officially maintained anymore. References will be removed where possible.
Reason: users who do not use #HTTPS for authentication may inadvertently send sensitive form data to third parties when a domain expires.
Use .ygg, ygg., and other temporary aliases at your own risk - consider this your notice.

Anyone here speaks DNSSEC?
I have a fundamental problem understanding DNSSEC. Perhaps one of you can help me grasp the error (mine or the one in the protocol).
If I am an attacker that can manipulate your DNS traffic, why should I respond to DNSKEY queries?
If I can manipulate DNS, I can just leave out the signature. As long as there is no side channel for DNSKEY queries, and as long as the traffic can be manipulated, I can completely "disable" DNSSEC.
And I'm not yet speaking about the problem with only the DNS resolvers verifying the signatuers (if they actually do it), instead of the clients. I'm thinking of something like HSTS, but for DNS queries...
Or do I have a fundamental error in understanding here?
Как проверить скорость DNS прямо в браузере: тест через DoH
Во про какую штуку узнал 🧐 Это намного информативнее, чем пинговать тыкать каждый адрес вручную в консоли
Браузерный DNS Speed Test позволяет проверить скорость DNS прямо во вкладке через DoH – без установки утилит и с учётом реального сетевого окружения
Проверка проводится на основании отклика самых посещаемых ресурсов, доступ к которым ограничен может быть.
DNS Speed Test
страница у меня не загружается без подорожника, с ним выдёт результаты иные, тк не для моей физической локации, а для ip прокси, поэтому перед тестом отключил, по этой причине некоторые тесты провалены (красные)
