Hello Folks,

I have noticed that in website stats something along the lines of "" could this be used to determine whether or not a surfer
is using broadband?

Or is there a better way?

Yes, I'm not sure what function is used to find an domain name from the
IP, but after you have it it's just preg_match for the word "dsl".

Not reliably. e.g. Just looked up my external IP with nslookup, and it's *

And I'm definitely on broadband.

The domain name for the external IPs from the network at my university
also have no mention of "dsl", or anything like that.

* it's not anymore, I've reconnected, in case anyone bad wanted to do
naughty things to my connection ;)

Only if all broadband users in the world connect from Great Britain with
MadeUpISP(tm) and that ISP has separate IP ranges for modem and broadband

I can think of three better ways:

1) Ask user
2) Perform a speed test
3) Optimize your site so line speed is not important
