Connecting with BNLS

[Newby]

Hi

what is the IP for bnls.valhallalegends.com?

I am currently trying to move away from VB and make a bot in C++.  I can't seem to connect to bnls under the "bnls.valhallalegends.com" address.

I've been looking at other simple C++ bots and how they connect and it shows it connecting to BNET with its IP address instead of "useast.battle.net".

Resolve the domain name to an IP. I suggest you look up WSAAsyncGetHostByName().

(GetHostByName() IIRC will work as well, but WSAAsync is a better bet.)

As I understand it, WSAAsyncXxx does not actually perform true asynchronous communications.

That is correct. It's only emulated, but it works well enough.

I don't use WSAAsyncGetHostByName(), though...the normal gethostbyname() has always worked for me.

A good way to find the IP of a domain is to open your command console and type
ping www.valhallalegends.com or ping bnls.valhallalegends.com

So smart guy...  Do you realize that the KB article you gave here appies to 16-bit Windows?

Winsock Applications that issue a WSAAsyncGetHostByName() against MS real mode TCP/IP Winsock.dll receive IP address in reverse order

A Winsock application such as Internet Explorer 2.01 or Netscape 2.02 running on Windows 3.1 with MS real mode TCP/IP stack will fail to connect a remote host when the application issues a WSAAsyncGetHostByName() to resolve the remote host name to IP address. For example, WSAAsyncGetHostByName() will return "99.88.77.66" if the remote host IP address is "66.77.88.99".

(emphasis mine).

Since all of our computers nowadays use IE 2.01 on Windows 3.1, and we definitely link to 16-bit Winsock.dll as opposed to ws2_32.dll....

Minus, I would almost call that a flame: don't do that again

Why what are you talking about Sir Zakath?

[Zakath]

Way to delete your flame before my reply went through. Good thing we've got something called browser caching.

You should use getaddrinfo() if it's available.  The best option is to create a dedicated thread to do DNS lookups, with the thread using getaddrinfo if the local Winsock supports it, or gethostbyname if there is no IPv6 support available.
