Any free isp's that will work on my Sega Dreamcast?

I hope this is not off topic. Does anyone know of any free isp's that work with the sega dreamcast? I had heard that there was a way to get netzero to work, but I don't want to sign up unless I know it will work for sure. Thanks in advance for any help you guys might be able to offer.
