DNS: Rewinding Network Norms (Part 2)

Chaos Lever Podcast

The intricacies of DNS, exploring alternatives, and unpacking Microsoft's ZTDNS as they unravel the web of network naming.

Digging Deeper Into DNS

Building on their previous discussion, Ned and Chris explore lesser-known alternatives to DNS and the evolution of network security protocols. They discuss NetBIOS, a system developed by IBM for internal network communications, explaining how it handled name resolutions within smaller network segments in a noisy and often inefficient way. They also detail the development of DNS security measures like DNSSEC and DNS over HTTPS, which play critical roles in protecting DNS against various threats. Highlighting Microsoft's latest initiative, Zero Trust DNS (ZTDNS), they explain its objective to boost network security by restricting DNS requests to only those that are approved.
