One of the lesser known features of the internet is the ability to create private networks using IP addresses reserved for exactly this purpose. These addresses come under the IP block 10.0.0.0/8 and allow a total of almost 17 millon different hosts. Anybody can use them to set up a private network for their office, home or, in this case, nation. Today, Collin Anderson, an internet security researcher funded by the University of Pennsylvania, says he has gathered evidence proving that Iran is using this approach on a national scale to create a private internet that is widely accessible within the country but hidden from outside. “Iran has broken from commonplace Internet addressing standards to create a private network that is only accessible within the country,” he says.
