Demon DNS

Just got this from Demon, my ISP of choice for a number of years:

Please note that with effect from Tuesday 24th. August the customer cacheing DNS servers (158.152.1.43 and .58) will no longer respond to queries unless they come from a Demon Customer IP address. This will have no effect on the majority of our customers who connect to our services via Dial Up, ADSL or Leased Line.

Is it just me or does this really suck?

Are we seeing the first steps towards a non-collaborative network? A network of compatible but segregated virtual spaces? Kind of defeats the whole concept of the internet really (but then that’ll just be my paranoïa kicking in again)…
