If you've got a speedy internet connection at home, but it seems slow, it's possible its' not the connection itself but the speed of your chosen DNS server.
DNS Check, Blacklist Check, DNS Tools, the DNS App from DNSSniffer has it all. With our DNS App you can check and troubleshoot DNS & mail server configurations. Tools Summary: DNS Check - Run a full DNS Check for a domain. Blacklist Check - Check if a mail server is blacklisted. (checks over 50 known blacklists) Email Check - Check if a mail.

To figure out if the DNS servers are part of the problem, check out namebench, a DNS server benchmarking app. namebench compares your existing DNS servers to a large list of other DNS servers, and shows you how they all perform.
Dns Server For Apple
- Primary Server: 1.1.1.1; Secondary Server: 1.0.0.1; Download on the App Store. There is no Mac app so you’ll have to manually configure. AdGuard has a DNS service in addition to an.
- Open Network Preferences and make sure that 127.0.0.1 is the only DNS server (network preferences - advanced - DNS - add 127.0.0.1) Things should begin to work nicely again. Once things are working, you can run dnsmasq without the -no-daemon and -log-queries options, so it will start in the background and you don't need to keep a Terminal.
When namebench launches, you'll see a window populated with your current DNS server addresses, and a few other settings you can modify:

Click Start, then go ahead and find something else to do for a while—the benchmarking process may take 15 minutes or more, depending on how many name servers it can see.
macOS High Sierra update:While the app still runs in High Sierra, you won't see any output. However, thanks to commenter Marc K., you can still see the output once it's done. Open Terminal and paste this command:
This will open the results page in your browser—including the below-referenced eye candy—so you can compare the various DNS that were analyzed. Thanks Marc!
After namebench has done its thing, your browser will open showing a page with results, including some 'eye candy' charts like this one...
The report may tell you your current DNS is the fastest, or it may have recommendations for other servers. Note: You may also see lots of scary messages about a DNS being hijacked; you really don't need to worry about these. (CHeck the FAQ for answers about hijacking, and anything else in the output).

namebench can also be built from source, so you could use it in Terminal, but I haven't tried that. It's not new code—the latest version (1.3.1) is from 2010. However, it seems to run fine in Sierra (and Mavericks before that). If you're curious about your DNS servers, I haven't found a better tool than namebench to investigate their performance.
