1. Battle.net : This is probably the most popular method of playing Starcraft over the 'Net. Battle.net support is built into Starcraft and the interface is very user-friendly. Most importantly, it's fairly easy to find games over Battle.net. There's even a "ladder" built in, so you can compete with other Starcraft players. However, Battle.net isn't perfect. Since there are so many users on it, you may have trouble connecting to it during Internet peak hours. Also, your games will lag a lot which can be a pain in the butt.

2. Kali : You can download a 15-minute trial version of Kali which emulates an IPX network with your Internet connection. The registration fee is $20. If you haven't already registered Kali from before, then I highly recommend that you don't waste $20. However, this is a great alternative to Battle.net especially if you really want fast, reliable games at all costs.

3. Kahn : If Battle.net and Kali don't satisfy your needs, then you can try Kahn. Kahn has a $15 registration fee, but you can try it for free for 21 days. It works in a similar way to Kali in which an IPX network is emulated. However, there are not a lot of Starcraft players on Kahn.

1. Local Area Network : 2 to 8 player IPX multiplayer gaming is supported.

2. Proxy/Firewall Method : If you have only one modem but several computers connected in a Local Area Network (LAN), you can install a Proxy server on the computer with the Internet connection. You must obtain a proxy server and configure the other computers on your network to access the Internet via the proxy. Then all users on the computers can access Battle.net, Kali, Kahn, etc, but the speed may be poor due to a heavy load on your modem. This process may be easier said than done since I don't have a network.
