I’ve been using the net.LookupHost(hostname_goes_here) function from the net package and found that at some version after 1.4.2 it stops using all the DNS servers listed /etc/resolv.conf and only uses the first one, if that fails it stops and returns error. Is that intentional or a bug?
It should still be iterating over all servers. However, note the comment starting on line 194. Is that the error you’re getting?
I opened a ticket on github and they linked me to another. The issue has been “resolved” in 1.7.2 (beta).
