Author Comments:
This combo adds getSubnetMask() to Blitz3D via a .dll and userlib that I wrote in Visual C++ and additionally adds a getBroadcastAddress() function written in Blitz which can be used to ping a LAN of any network class type. I originally created this to "fix" BlitzPlay which is limited to a class-C network assumption and additionally doesnt even use the broadcast address for that assumption but instead pings 255 ip addresses. With this code multiplayer LAN searches can be conducted instantly on any network class. Heres a link to the .dll/userlib www.alessigames.com/codeArchives/ipHelper.zip Theres a onesComplement() function included as well which is used in the getBroadcastAddress() function.
