getaddrinfo for IPv6 always fails with error code 11268096 - c++

Question

Edit: Upon Checking on IPv6 Test I Found out My ISP does not provide IPv6... otherwise this code is good
getaddrinfo() always fails for IPv6 with the error code 11268096, but it is successful for IPv4.
Setting Hint.ai_family = AF_INET6; is what triggers the error, but I do not know why.
Also, how do I get the sin_port/sin6_port in numbers? I am always getting port 0.(As #Remy Lebeau pointed out I am only asking for IP of the Domain so it won't output port...)
void GetAddrInfoFromHostNameIPV6(const char* DomainName, addrinfo* Result, bool& IsSuccessful)
{
IsSuccessful = false;
addrinfo Hint;
addrinfo* Return = nullptr;
int ErrorCode;
memset(&Hint, 0, sizeof(Hint));
Hint.ai_family = AF_INET6;
Hint.ai_socktype = SOCK_STREAM;
//Hint.ai_socktype = SOCK_DGRAM;
ErrorCode = getaddrinfo(DomainName, NULL, &Hint, &Return) << '\n';
if (ErrorCode != 0)
{
std::cout << "\n Error GetAddrInfoFromHostNameIPV6() Failed with Error Code: " << ErrorCode << " in GetAddrInfoFromHostName In: NW_P!";
}
else
{
*Result = *Return;
char IpAddress[INET6_ADDRSTRLEN];
uint16_t Port;
inet_ntop(AF_INET6, &((sockaddr_in6*)((Result)->ai_addr))->sin6_addr, IpAddress, INET6_ADDRSTRLEN);
Port = *(&((sockaddr_in6*)(Result->ai_addr))->sin6_port);
std::cout << "\n IPV6 Address of Domain '" << DomainName << "' Is " << IpAddress << " With Port: " << Port;
IsSuccessful = true;
}
if (!IsSuccessful)// For the safe of readability
{
std::cout << "\n Error GetAddrInfoFromHostName() Failed in NW_P!\n";
}
}

You are bit-shifting the error code 10 bits to the left before assigning it to ErrorCode.
Decimal 11268096 is binary 101010111111000000000000. Notice all those extra zeros on the right?
You need to get rid of << '\n' after getaddrinfo() returns, it doesn't belong there, as you are not outputting the error code to std::cout on that line of code.
Removing the bit shifting, the real error code is 11004 (binary 10101011111100) which is WSANO_DATA:
Valid name, no data record of requested type.The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.
You can pass the error code to gai_strerror() to get a human-readable string for your error message output, eg:
std::cout << "\n Error GetAddrInfoFromHostNameIPV6() Failed with Error Code: " << ErrorCode << " (" << gai_strerror(ErrorCode) << ") in GetAddrInfoFromHostName In: NW_P!";
As for the port number being 0, you are not asking getaddrinfo() to parse any service name/port string as input (the pServiceName parameter is NULL), you are only asking for translating a domain name into an IP, so it is not going to output any port number. Port numbers are not used by Domains themselves. Port numbers are used by services (HTTP, etc) that are running on servers where domains/IPs point to.
On a side note, you are leaking the addrinfo list that getaddrinfo() outputs. You need to call freeaddrinfo() when you are done using the list.
