How much EU is in DNS4EU?

Summary

This is another post that started after several toots on mastodon. Most of the things presented here were already tooted by other people, but I think this is a good chance to write a mini tutorial about what to look at. We’ll use DNS, whois, BGP and your favourite search engine. What is DNS4EU?# To quote the web page: Supported by the European Union Agency for Cybersecurity (ENISA), the European Union’s DNS4EU secure-infrastructure project provides a protective, privacy-compliant, and resilient DNS service to strengthen digital sovereignty and security for EU citizens, governments, and critical infrastructure. First things first# The first thing your computer does is to do a DNS lookup, so let’s do the same: $ dig ns joindns4.eu +short ns63.cloudns.net. ns64.cloudns.uk. ns61.cloudns.net. Searching for clouddns you’ll find that they are a European company. Going one step further we can check the IPv4 and IPv6 addresses of the three name servers above and see that all of them are from providers within the EU. $ for i in $(dig ns joindns4.eu +short); do host $i; done ns61.cloudns.net has address 109.201.133.168 ns61.cloudns.net has IPv6 address 2a00:1768:1001:9::168 ns64.cloudns.uk has address 185.206.180.150 ns64.cloudns.uk has IPv6 address 2a0b:1640:1:1:1:1:15ee:539e ns63.cloudns.net has address 51.210.104.220 ns63.cloudns.net has IPv6 address 2001:41d0:304:200::455b You can check all of them yourself by using whois on the command line. I’m leaving that out to keep this post short. EU:NON-EU 1:0 So let’s look at the website: $ host www.joindns4.eu www.joindns4.eu is an alias for 142290803.sites.hscoscdn-eu1.net. 142290803.sites.hscoscdn-eu1.net has address 141.101.90.98 142290803.sites.hscoscdn-eu1.net has address 141.101.90.99 142290803.sites.hscoscdn-eu1.net has address 141.101.90.96 142290803.sites.hscoscdn-eu1.net has address 141.101.90.97 142290803.sites.hscoscdn-eu1.net has IPv6 address 2a06:98c1:3200::90:0 142290803.sites.hscoscdn-eu1.net has IPv6 address 2a06...
