Acceptance tests don't run on IPv4-only systems
Since we hardcode [::1]:37000
(and a few others) in acceptance_test.go
, the acceptance tests fail if IPv6 is disabled on a system. Tests fail with "bad address" messages.
I thought I'd never see such a system again in my life, but it turns out that when running inside docker on my local machine, there's no IPv6 stack. So the tests fail.
