How to change default DNS in Mac OS?

Question

Domain Name System

Good afternoon!

I use a Mac OS laptop at work. I connect to the corporate Wi-fi network - only in this case I can get access to a number of internal company services.

Faced with the fact that periodically "does not let" these resources. As it turned out - the wrong DNS. I go into the network settings and see the default DNS addresses for this network (photo below).



At the same time, when executing the command

scutil --dns | grep 'nameserver\[[0-9]*\]'

in the Terminal, I see that the system uses DNS 8.8.8.8.



Forced prescription of the "correct" DNS addresses in the network settings does not help. Previously, this happened, I decided I don’t even understand how, I just rebooted the computer a couple of times, reconnected to the network 5-6 times in a row.

But I want to understand the real cause of the problem.

Notebooks MB Air 11.6 "2014, Mac OS 10.14.6 Mojave

UPD : DNS returned to normal after the weekend. On Monday I went to work and worked correctly. The reason is still not clear. It will most likely happen again when rebooting.

Answer 1

strange. maybe there is some software that forks dns.
as an option: install dnsmasq, configure it and register it in the connection settings.

Answer 2

On all other interfaces, delete DNS, they are not needed there anyway.
