🚀🌐 NAMESERVER – “NGƯỜI DẪN ĐƯỜNG” CHO WEBSITE
Mỗi khi bạn nhập tên miền, Nameserver sẽ giúp chuyển đổi sang địa chỉ IP để trình duyệt tìm đúng máy chủ 📡
Đây là bước quan trọng giúp website truy cập nhanh, ổn định và chính xác.

112 – Was sind Nameserver und Cloudflare
Nameserver sind entscheidend für die Funktion des Internets, da sie die Benutzerfreundlichkeit durch die Umwandlung von leicht merkbaren Domainnamen in numerische IP-Adressen sicherstellen. Ohne Nameserver müssten Benutzer sich IP-Adressen merken, um Websites zu besuchen, was sehr unpraktisch wäre.https://nerdcafe.online/episoden/112-was-sind-nameserver-und-cloudflare/
Just added 2 more name servers for one of my domains. Why? Why not :P
```
# dig ns sahil.rocks +short
ns2.afraid.org.
ns3.he.net.
ns1.first-ns.de.
colin.sahilister.net.
ns2.albony.in.
ns4.he.net.
marvin.sahilister.net.
puck.nether.net.
ns0.1984.is.
robotns3.second-ns.com.
ns1.1984.is.
ns-global.kjsl.com.
```
So, while working on some #botnet research, I discovered a domain for which a #nameserver was configured with the name ns1.nulled-ns.com and ns2.nulled-ns.com. As more I figure out about this unknown authoritative nameserver, as more I am convinced that the entire purpose of the nameserver is to provide name services for malicious domain names, such as #c2 or #phishing domain names.
Happy about anyone commenting, or reaching out to me with more insights.
Cheers!

Während ich mir die Performancergebnisse zu meinem metalhead.club CDN angesehen habe, ist mir aufgefallen, dass die Namensauflösung einen beträchtlichen Teil der Ladezeit für internationale User ausgemacht hat.
Woran lag's? An CNAMES!
Wieso CNAMES problematisch sein können, erfahrt ihr in diesem zweiten Blogpost, den ich während meiner Arbeiten am CDN geschrieben habe:
"Globale DNS-Auflösung durch Verzicht auf CNAMES beschleunigen" -

Sagt mal - kann das wirklich sein, dass es außer Cloudflare keinen globalen DNS-Nameserveranbieter gibt, der 100 % Ökostrom einsetzt? 🤔
Es gibt zwar ein paar, die nur mit Ökostrom laufen, aber die sind dann mit ihren Nameservern nur regional aufgestellt. :(
As of today, #DNS4EU is live. A project that started somewhat of 3 years ago. Now, it's public and live, promising secure and resilient service to #EU citizens, strengthening the #European #cyberresiliency .
More here.
I queried my own domain name out of interest. The EU protective resolver resolves in 340 ms, whereas #Cloudflare and #Quad9 both resolve within 50 ms.
The unfiltered resolution however resolves within 50 ms as well, revealing that the filtering introduces a slight performance penalty.
