  •  There are plenty of ways to block hosts (0+ / 0-)

    that are not located within one's jurisdiction. The easiest clean way to block a host is to have routers send back ICMP Type 3, Code 1 "Destination Unreachable" packets in response to TCP connection requests and UDP packets that are sent to known bad actor IP addresses.   Its doesn't matter if one can resolve a domain name when one cannot send TCP or UDP packets to the target host address.

    •  And there are ways around that, too (0+ / 0-)

      Proxies, VPNs, and so forth let you get around that.  Unless, of course, all routes outside of the jurisdiction are blocked.

      Sure, there's deep packet inspection and all that, but if the traffic's encrypted, that doesn't work.  And if all encrypted traffic is blocked, then the net's not of much use for commerce (including internal corporate traffic over the internet).

      •  VPNs, proxies, and anonymizers all use (0+ / 0-)

        IP addresses; therefore, they can be blocked.   SIGINT-style traffic analysis techniques can be used to address the encrypted data problem (not that that would be a problem if NSA were to get involved in the enforcing the law).  I used to design high-speed switch and router software for one of the major telecommunications equipment manufacturers.  I also spent several years working in NSA's R Group.

        •  If you're willing to crack down hard enough (0+ / 0-)

          then yes.  China seems to be fairly successful (so far) at this, and some countries have simply physically cut themselves off from the outside net.  But I'm guessing that there's still enough notion of a rule of law (not to mention big economic interests) in this country that we won't go that far.  I think even the MPAA is smart enough to realize this.  I think that, at any rate.
