Does go test -run TestIgnoreLameReferrals net reliably fail for you?

If so, can you run the process under strace (or whatever OS X has) and/or tcpdump to see what's going on? That test should be self-contained and not talk to the network at all. It's puzzling where 220.255.2.153 would come from.

Oh, do you have www.golang.org in your /etc/hosts by any chance?

/etc/hosts

# 220.255.2.153 www.golang.org

go version

go version go1.7 darwin/amd64

Thx!
