DNS flag day

1 Feb 2019

On 1 February 2019, major Domain name system (DNS) providers such as CISCO, CZ.NIC, Google, Cloudflare, and Facebook, released new software updates that will stop supporting the old workarounds that existed for the DNS resolution process and allowed users to bypass the Extension Mechanisms Protocol for DNS (EDNS). EDNS is a set of extension mechanisms to expand the size of the DNS message as it goes through its query, which allows more information to be included in the communication between each host in the DNS resolution process. Because of the efforts to accommodate a few DNS systems, including EDNS, that are not in compliance with DNS standards established two decades ago,  the providers have decided to stop supporting old workarounds.

Cybersecurity is among the main concerns of governments, Internet users, technical and business communities. Cyberthreats and cyberattacks are on the increase, and so is the extent of the financial loss. 

Yet, when the Internet was first invented, security was not a concern for the inventors. In fact, the Internet was originally designed for use by a closed circle of (mainly) academics. Communication among its users was open.

Cybersecurity came into sharper focus with the Internet expansion beyond the circle of the Internet pioneers. The Internet reiterated the old truism that technology can be both enabling and threatening. What can be used to the advantage of society can also be used to its disadvantage.
