Cloudflare 的 1.1.1.1 把 A 放在 CNAME 前面搞爆 glibc 的 DNS resolver

有陣子了,上個月的時候 Cloudflare 的 1.1.1.1 因為在改善記憶體用量,導致 A record 有可能在 CNAME record 前面,結果把 glibc 的 DNS resolver 炸了:「What came first: the CNAME or the A record?」,在 Hacker News 上也有些有趣的討論:「What came first:...

RFC 7757: Explicit Address Mappings for Stateless IP/ICMP Translation, T. Anderson, et al., https://www.rfc-editor.org/info/rfc7757 #RFC This document extends the Stateless IP/ICMP Translation Algorithm (SIIT) with an Explicit Address Mapping (EAM) algorithm and formally updates RFC 6145. The EAM algorithm facilitates stateless IP/ICMP translation between arbitrary (non-IPv4-translatable) 1/2

RFC 7755: SIIT-DC: Stateless IP/ICMP Translation for IPv6 Data Center Environments, T. Anderson, https://www.rfc-editor.org/info/rfc7755 #RFC This document describes the use of the Stateless IP/ICMP Translation Algorithm (SIIT) in an IPv6 Internet Data Center (IDC). In this deployment model, traffic from legacy IPv4-only clients on the Internet is translated to IPv6 upon reaching the IDC 1/3

Only started to read into this "new" , informational #IETF #RFC, called "#Multicast Lessons Learned from Decades of Deployment Experience", but it's already a super interesting read:

Multicast Lessons Learned from Decades of Deployment Experience

This document gives a historical perspective about the design and deployment of multicast routing protocols. The document describes the technical challenges discovered from building these protocols. Even though multicast has enjoyed success of deployment in special use-cases, this draft discusses what were, and are, the obstacles for mass deployment across the Internet. Individuals who are working on new multicast related protocols will benefit by knowing why certain older protocols are no longer in use today.

Thanks for correcting me everyone!

WHO AT #IETF decided to allow this #Enshittification???
