1.1.1.1 Question


#1

Why am I getting different answers. I have made a name resolution at 1.1.1.1 and at 8.8.8.8. At 8.8.8.8 I got the right answer.

Server:  one.one.one.one
Address:  1.1.1.1

Name:    download.cdn.proxmox.com
Addresses:  2607:5300:60:5506::81
	  66.70.154.81
Aliases:  download.proxmox.com

Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Name:    de.cdn.proxmox.com
Addresses:  2a01:7e0:0:424::249
	  212.224.123.70
Aliases:  download.proxmox.com
	  download.cdn.proxmox.com

I get the same answers from both. But your second query is for ‘de’ instead of ‘download’. So that’s probably a geographic response.

iRetina:~ scott$ host download.cdn.proxmox.com 1.1.1.1
Using domain server:
Name: 1.1.1.1
Address: 1.1.1.1#53
Aliases:
download.cdn.proxmox.com has address 66.70.154.81
download.cdn.proxmox.com has IPv6 address 2607:5300:60:5506::81

iRetina:~ scott$ host download.cdn.proxmox.com 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:
download.cdn.proxmox.com has address 66.70.154.81
download.cdn.proxmox.com has IPv6 address 2607:5300:60:5506::81

Those were just the answers. I entered the following commands in Windows:

nslookup download.proxmox.com 1.1.1.1
nslookup download.proxmox.com 8.8.8.8

After that I received the answers.

Both answers are correct. Though the localisation seems not to be accurate on one of the nameservers. Using 8.8.8.8 points you to CDN nodes in DE while 1.1.1.1 points you to another egde of their CDNs network, US probably.

I get the same results.

Run this:

https://1.1.1.1/help

After the test is finished, Paste the generated link here. Imho this is something that should be looked into. Isuues like this one can cause performance problems since you’d download from edges in CA or US.

Who can say anything about that? Is that normal? Then 1.1.1.1 is still not usable for me.

:wave: @roswitina,

See 1.1.1.1 supports ECS?
