I use GRC's DNS Benchmark tool[1] for this whenever I set up DHCP somewhere, and the results are sometimes surprising. If you're on a *nix or macOS, it runs well under Wine.

- compumike 8y agoYes, I just used dig's reported timings: dig triplebyte.com @1.1.1.1 | grep 'Query time' ;; Query time: 2 msec dig triplebyte.com @8.8.8.8 | grep 'Query time' ;; Query time: 21 msec but could imagine doing a more thorough benchmark like the one you linked if my results weren't so dramatically different!
- geek_at 8y agowow didn't think it was this much of a deal but can confirm dig triplebyte.com @1.1.1.1 | grep 'Query time' ;; Query time: 5 msec dig triplebyte.com @8.8.8.8 | grep 'Query time' ;; Query time: 35 msec
- PascLeRasc 8y agoThis is great if you're at home or there's no IT team like in the article (a dream come true!) but if you're in a more corporate network these kinds of tools will usually ping NSFW servers. I also prefer namebench (https://github.com/google/namebench https://github.com/google/namebench) since it runs at the command line.
- scolby33 8y agoWhat sort of DNS server is NSFW? I can't imagine that any DNS benchmark would need to reach out to anything other than a DNS server. If I recall correctly, the GRC DNS benchmark uses a set of domains set up expressly for the benchmark itself.
- bscphil 8y agoDisclaimer, I haven't looked at GRC explicitly, but often tools like this will * check whether a range of domains are censored by the DNS * lookup a bunch of domains and ping them to check whether the DNS server is returning properly localized addresses using EDNS - Cloudflare DNS is a good example of one that was not (at least a few months ago)
