You can still see subnets though which was the original point.

With many ISPs handing out /64s and others handing out /48s and /56s to households, it's difficult to tell a subnet from another IP.

Even still, this information is pretty useless. So what if you know my current subnet is 3a80? That won't help you get past the firewall.
