// On a machine that supports IPv6, msquic will resolve `localhost` to `::1`, which `IPAddress.Any` will not accept.
// (To make it work, you'd need to use `IPv6Any`, as `ListenAnyIP` does.) As a result, a client built on msquic,
// e.g. `HttpClient` on Windows, will not be able to make HTTP/3.0 requests to `localhost:5001`. HTTP/1.x and
// HTTP/2.0 will still work.
// Example: https://github.com/dotnet/runtime/issues/108259
// msquic: https://github.com/microsoft/msquic/issues/1181 (resolve both)
// System.Net.Quic: https://github.com/dotnet/runtime/issues/82404 (improve consistency with sockets)
