From all my tests it performs better than local ISPs and google's DNS servers. How fast can it process your query (is answer cached, is the server overloaded etc)Ĭloudflare is claiming to provide safe and secure service.Perceived DNS server performance depends on two factors: The latency will also depend on the current load of the DNS server. If the DNS server doesn't have this domain stored in the cache, it will perform recursive lookup before returning to your client with the answer.Īs you can imagine, there will be significant difference in latency depending on at which stage you will get the address resolution.DNS server is checking its cache and if the domain is there, it will reply with IP address.DNS client is contacting upstream DNS server configured in /run/systemd/resolve/nf.DNS client is checking /etc/hosts for static entries.home and resolve - I am not sure how did it work, perhaps you are directly connected to the provider's network and you were able to reach provider's DNS via LLMNR So how it works The command you used, "systemd-resolve protocol" - is attempting to complete the domain with. Its purpose is to point applications, which would try to get directly to DNS server, back to the systemd-resolved DNS client. The file /etc/nf is symlinked to /run/systemd/resolve/nf You can check your currently configured DNS servers with: systemd-resolve -statusġ27.0.0.53 is your loopback IP which is bounded to your local DNS client. Systemd-resolve (without 'd' ) is an app that can be used for interfacing with the DNS client. Systemd-resolved (with the 'd' ) is a service which is your DNS client on your local machine. When I google these last 2 DNS numbers, Akamai technologies which is connected to Century Link my ISP comes up.Ĭan somebody explain in plain language what is gong on?įinally should I switch to CloudFlare or some other DNS in the table or just stick to what I have? Information acquired via protocol DNS in 150.9ms. I was like "Great, no need to change my DNS is already running at top speed"īut when I ran this: $ systemd-resolve protocol It forwards DNS requests to whatever upstream DNS servers you specify. I googled the first DNS server and found this definition on AskUbuntu:ġ27.0.0.53 is the address of the local caching stub resolver. These are the results: :~/dnsperftest$ bash. In trying to answer these 2 questions I ran the following to scripts: What is my current DNS resolver is: is it 127.0.0.53 (Ubuntu) or 198.105.244.23 (Century Link which is my current ISP)? Will switching to CloudFlare DNS resolver 1.1.1.1 speed things up for me?
