> We want to support Arrow Flight compatibility protocol in ClickHouse ([https://github.com/ClickHouse/ClickHouse]). Our code needs Ipv6 support.
> In our code I wrote:
> {code:java}
> std::string host = "[::]";
> int port = 9993;
> arrow::flight::Location location;
> auto status = arrow::flight::Location::ForGrpcTcp(host, port, &location);
> std::cerr << "Status=" << status.ToString() << std::endl;
> std::cerr << "Location=" << location.ToString() << std::endl; {code}
> The output seems to be ok:
> {code:java}
> Status=OK
> Location=grpc+tcp://[::]:9993{code}
> After that I initialized FlightServerBase using method Init(options).
> In flight library I wrote next 3 lines before [code|#L825]
> {code:java}
> std::cerr << "Location=" << location.ToString() << std::endl;
> std::cerr << "Host=" << location.uri_->host() << ", Port=" << location.uri_->port_text() << std::endl;
> std::cerr << "Host:Port=" << location.uri_->host() << ":" << location.uri_->port_text() << std::endl;{code}
>  
> The output is:
> {code:java}
> Location=grpc+tcp://[::]:9993
> Host=::, Port=9993
> Host:Port=:::9993
> E1103 03:18:01.978794160 612780 server_chttp2.cc:40]
> {"created":"@1604362681.978626229","description":"Name or service not known","errno":-2,"file":"../contrib/grpc/src/core/lib/iomgr/resolve_address_posix.cc","file_line":108,"os_error":"Name or service not known","syscall":"getaddrinfo","target_address":":::9993"}{code}
> Location returns host without square brackets that must be used in addresses with port. The problem is here:
> {code:java}
> std::stringstream address;
> address << location.uri_->host() << ':' << location.uri_->port_text();{code}
> The same issue is also observed in the client [code|#L845]
