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

brnt-bam-1.inet.ntl.com *

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 ;)
