近期遇到的奇怪问题🤔
天津地区运营商上游默认提供的dns仿佛无法正确解析alidns的doh域名(其他地方不确定，至少北京前几天应该没这个问题)，具体表现为dns服务器返回alidns的ip为127.0.0.1或0.0.0.0
然而指定了dns比如8.8.8.8或者114.114.114.114均能够正常返回alidns的域名( https://tool.chinaz.com/dns/dns.alidns.com )
不知道大家所在地区的运营商有没有同样的问题
Did we mention we are #hiring? ISO a Tier-2 Technical Support Engineer to join the team, specifically in the UTC-3 to -6 timezones.
Please take a look and share!

My list was getting bigger than a Fedi post could hold, so it is now hosted on Codeberg, an alternative to GitHub or GitLab, but based out of Germany. 👍

The Russians aren't coming, they are already here. Without most anyone realizing, they've created an entire malicious adtech industry whose story is just as complex as the Chinese organized crime we're now realizing from their ventures into pig butchering.
VexTrio is just one Russian organized crime group in the malicious adtech world, but they are a critical one. They have a very "special" relationship with website hackers that defies logic. I'd put my money on a contractual one. all your bases belong to russian adtech hackers.
Today we've released the first piece of research that may eventually prove whether I am right. This paper is hard. i've been told. I know. We've condensed thousands of hours of research into about 30 pages. @briankrebs tried to make the main points a lot more consumable -- and wrote a fabulous complimentary article : read both!
There's so much more to say... but at the same time, between ourselves and Brian, we've released a lot of lead material ... and there's more to come. I've emphasized the Russian (technically Eastern European) crime here, but as Brian's article points out there is a whole Italian side too. and more.
We've given SURBL, Spamhaus, Cloudflare, Domain Tools, several registrars, and many security companies over 100k domains. They are also posted on our open github.
Super thanks to our collaborators at Qurium, GoDaddy Sucuri Security, and elsewhere.

在 #DNS 体系中，注册商处填写的 NS 记录与权威服务器上返回的 #NS 记录扮演着不同但关联的角色：
注册商设置的 NS 记录构成了域名的委托链，它是全球递归解析器寻找权威服务器的起点，决定了 谁被信任来回答这个域名的查询；而权威服务器自身在响应时返回的 NS 记录，则属于该区域的区域数据，通常用于通知下游服务器该域的权威来源，常见于区域传输或缓存更新。
尽管 RFC 建议两者保持一致以确保清晰和可维护，但技术上并不要求强制同步 —— 只要权威服务器能正常响应查询，即使其返回的 NS 记录指向一个未注册或看似荒诞的域名，递归解析器仍会接受其提供的 A、#CNAME 等答案。因此，你可以在注册商处安全使用真实、可达的 NS 名称，同时在自己的 zone 文件中保留个性化的 NS「签名」，作为一种无害而有趣的极客彩蛋。
