The body that UN types would like to run critical pieces of the internet in place of ICANN, namely the ITU, has not, as of today, bothered to ensure that its own class B IP address range was protected from hijacking. Fortunately for it the administrator (RIPE) locked the address range but it did so over a year ago and the ITU has yet to do anything about it.
ICANN has certainly not been the perfect body we would all like but it does seem to understand the interwebnetthingy unlike the ITU.
