🚀🌐 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!
Welcher #Domain #Registrar empfiehlt sich denn für .de Domains?
Zwingende Features:
- Setzen der autoritativen #Nameserver
- #DNSSEC
- ≤ 10 €/Jahr netto
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.

};Kann es sein, dass die #telekom #nameserver #dns die #TTL nicht unbedingt befolgen?
Ich habe (#AusGruenden) hier einen RR auf 60 Sekunden gesetzt und irgendwie hat's jetzt (ziemlich genau?!) eine Stunde gedauert, bis die Updates an den LTE-VPN-Knoten durch waren...
What would one use for an internal, authoritative nameserver these days on Debian? Shall I go with good old Bind as I have been for decades or is there something better?
(Just a handful of zones, definitely keeping text-based zone files, tooling for automatically generating reverse zones could be nice...)
