So I am using OpenDNS on my home network to block Nintendo's servers connecting to my 3DS when using the household wifi. I would like to know if all of these domain names that i have blocked are sufficient enough? https://gyazo.com/07f0b6c0d92f6d9b95b5aae496a7323e I have blocked both USA and European domain names just in case. Will blocking "cbvc.cdn.nintendo.net" prevent the my system from having a blocked browser unless i update in USA as well as Europe? Or does Europe have a different domain for the browser check?
