I have tested locally before pushing the code, nothing is failing. Let me re-trigger the PR.

The test failure for the new pickfirst policy seem to be because the DNS resolver is resolving localhost to both the IPv4 and IPv6 addresses, while the server listens only on the IPv4 address. Can you change the following line to la := "[::]:0" and see if the test passes?

grpc-go/test/end2end_test.go

Line 612 in 38a8b9a

la := "localhost:0"

This should make the server listen on both the IPv4 and IPv6 localhost addresses.
