networking - Unable to reach www.google.com on mac

Question

In the past 2 weeks I started having an issue w/ search on google. I enter a search term in the search box or in the address line and chrome takes a long time until something happens.

At first it would say it couldn't reach the site and then immediately load the search results, but now it just says

This site can’t be reachedCheck if there is a typo in www.google.com. DNS_PROBE_FINISHED_NXDOMAIN

I tried searching in google from firefox and got the same behavior. I pinged google.com in the terminal and the ping looked fine, but when I pinged www.google.com the ping timed out

~ % ping google.com

tried restart of the mac and nothing changed

I tried following the suggestions here and it didn't work https://stackoverflow.com/a/65695189/2482564

mac version:11.2.3

any ideas on how to move forward?

Answer 1

As it was explained to me by a colleague the problem comes from my ISP DNS server,

I had to change the DNS on the mac from the default DNS to 8.8.8.8

using System Preferences-> Network. Click the Advanced button then go to the DNS tab. Click on the + button. Enter 8.8.8.8

it was explained in one of the comments here - https://stackoverflow.com/a/65695189/2482564

You can read a little about the google public dns - https://developers.google.com/speed/public-dns
