The unittest[1] does not work when www.digitalmars.com resolved to a IPv6 address.

https://github.com/dlang/phobos/blob/35e9f2fbbaab75815c01a7e6b7d207e98afb9d56/std/socket.d#L986 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.
