What about just using the IP block that you come from. Im sure there is a list of what IP's are assigned to the cable/DSL companies somewhere....:)
Just a guess...

But I think your browser would warn you about that. The most simple way would be for the web server to ping you, say with a 500 byte packet, and based on the reply time, determine your speed. To be more accurate, it could ping with a small packet, then a big one to analyze the difference. I've got a cable modem. Two different pings: Pinging www.novell.com [192.233.80.5] with 32 bytes of data: Reply from 192.233.80.5: bytes=32 time=110ms TTL=34 Reply from 192.233.80.5: bytes=32 time=152ms TTL=34 Reply from 192.233.80.5: bytes=32 time=109ms TTL=34 Reply from 192.233.80.5: bytes=32 time=111ms TTL=34 Ping statistics for 192.233.80.5: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 109ms, Maximum = 152ms, Average = 120ms C:\Documents and Settings\church>ping www.novell.com -l 500 Pinging www.novell.com [192.233.80.5] with 500 bytes of data: Reply from 192.233.80.5: bytes=500 time=114ms TTL=34 Reply from 192.233.80.5: bytes=500 time=122ms TTL=34 Reply from 192.233.80.5: bytes=500 time=146ms TTL=34 Reply from 192.233.80.5: bytes=500 time=144ms TTL=34 Ping statistics for 192.233.80.5: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 114ms, Maximum = 146ms, Average = 131ms As you can see, even though the the second ping data size was over 10 times bigger, the time went up very little, indicating your connection isn't the bottleneck, but the latency through numerous router hops was. Try the same on a slow connection, and you'd see a much bigger difference between the two.
