Ep 124 - April 8 - DNS and can it be good?
  • Nothing like waiting for new toys – I was hoping my new NAS was arriving today – but no – not even shipped.
  • DNS – Domain Name System
  • PhoneBook of the internet translates human readable names (domain-names) to IP-adresses that can be used by computers.
  • It works like a tree – with root servers – top–domains – domains and hosts or subdomains. To find a name you traverse the tree (or the DNS-server you use traverses the tree).
  • Caching is used to make the loads lower.
  • DNS is interesting since it old and built by trust – and today that is not very safe.
  • We can secure our DNS-data by signing it – hindering DNS-servers providing wrong information or spoofing DNS-names.
  • We can encrypt the DNS-querys increasing privacy.
  • Which DNS-server are you using – who can se what you access? Google? Your telco?
  • I have switched to use Quad9 – that provide a non-logging DNS-server to secure your privacy. You can also use their DNS-over-TLS or DNS-over-HTTPS solution to increase your privacy more.
  • Quad9 also have block-list that stops you from getting to malicious sites (optional).
  • Quad9.net
