Also here, IPv6 can cause exceptions.
std/socket.d does not fully support IPv6, such as GetHostByAddr().
Perfecting std/socket.d to fully support IPv6 is certainly the best, but it's a bit of a workload.
So it may be a short-term solution to temporarily handle unittest to make it work properly. Otherwise, auto-tester of PR will be interrupted frequently.
