A Milestone Day for the Internet?

On January 1, 1983, not a single one of us noted a very important thing happening: the DoD’s “ArpaNet” network was implementing the switchover to the TCP/IP inter-networking protocols for the then-quasi-experimental “Internet.” You would have had to be awfully prescient to recognize what we recognize today — that the transformative global network was as of that date in place. Something similar might — or might not — have happened this past Thursday, when the US Department of Commerce and ICANN, the Internet Corporation for Assigned Names and Numbers, executed a strangely-titled “Affirmation of Commitments.”

But the gist of it can be summarized as follows (and if you want more detail about the background here, which is really quite extraordinary, have a look at Chap. 10 of my Jefferson’s Moose book). ICANN, a private non-profit corporation, was formed in 1998, and the US government handed over responsibility to it for management of the Net’s “domain name system” — the complex global network of registration services and databases and nameservers that allow the net to accomplish the remarkable task of resolving domain names (“”) into IP addresses (necessary for the correct routing of messages). In the original “Memorandum of Understanding” between DoC and ICANN, the government retained some “oversight” over ICANN — basically, a kind of “If you act in some way we really don’t like, we’ll take it all back” clause. The government also retained final authority to make any changes in the “Root Zone file” — the little file that resides on 13 “Root Servers” around the world that sits at the apex of the millions and millions of interlocking databases that comprise [...]
