How will the browser behave?

Question

Domain Name System

How will the browser behave if round-robin DNS is configured, and one of the given addresses will not be available?
Will it connect in vain, or will it realize that the address is not available and try to connect to another one?

Answer 1

And you test and tell us.
As far as I know, it will connect even if one of the addresses is not available.
At least when I organized a second channel in my office and made a similar setting in the DNS, then the support practically stopped receiving calls from customers about the unavailability of the service when one of the channels was not working.
