So looking around to improve my knowledge on how DNS works I fell into a “well hidden” chrome functionality that looks really cool!!
Chrome tries to resolve urls while the user types (DNS Prefetching) and it has an internal functionality to analyze all the relevant events.
Try to type in the address bar
chrome://net-internals/#dns
A couple of screen shots of two tools included in the functionality…

Testing a url
Go check it out…
