NET Virtua (Brazilian ISP) is not connecting to Cloudflare dns


#1

I can acess 1.1.1.1 website here
But I traceroute to 1.1.1.1 and 1.0.0.1. I found out that NET Virtua (an Embratel ISP subsidiary) is only connecting to NET Virtua and Embratel servers. Not CloudFlare dns.

This is my computer connected to internet via NET Virtua ISP (I am in Rio de Janeiro):
1.1.1.1
1.0.0.1
208.67.222.222 (OpenDNS, which has servers in São Paulo city)
8.8.8.8 (Google DNS).

I also uploaded a printscreen from a friend of mine connected to internet via Vivo GVT ISP (you can see he can connect to CloudFlare DNS, I cannot).

So as you can see Net Virtua ISP and Vivo GVT ISP, NET Virtua is not connecting to CloudFlare dns servers.

And as a consequence, even if CloudFlare has server in Rio de Janeiro (www . cloudflare . com / en / network /), your ping is very similar to OpenDNS (who has brazilian servers only in São Paulo www . opendns . com / data-center-locations /) ~ 17ms
Making Google DNS still the fastest DNS in Rio de Janeiro (~ 9ms)

As I am a new Cloudflare community user and I cannot upload more than 2 images, I uploaded all images here: https://imgur.com/a/hcNwQ

Here are my results:

My router is a MitraStar model GPT-2541GNAC-GV


#4

The less elegant solution rightnow is using 1.0.0.1 and 8.8.8.8 it seems as primary and secondary ipv4 dns.

cloudflare ipv6 dns seems to be unaffected.
