You do know there are alternative DNS roots...not just the 13 you guys have been talking about.
They are not all under US control. (Unifiedroot is Dutch)
If you think it's possible that the US government would shut down the ICANN/IANA roots, it might be smart to get the info you need to make a quick switch to one of the ones on this list and keep it in a safe place.
Well... Yes and no...
While you might be able to actually connect to http://reg.for.free/
(click to find out), can anyone else? Does anyone here own a ".geek" or a ".free" domain? *Would* you ever use one? (That's actually a different question, but it illustrates how much alternate DNS roots are trusted. See here for a good FAQ on OpenNIC and .com, etc.
) You don't see .geek or .anarchy or other TLDs like those in use.
Basically, alternate DNS systems need to have ubiquitous usage in the same way that Microsoft Office documents are ubiquitous. i.e. If everyone else is using X, then you need to as well, and no matter if something else is better, if nobody can access it, then it's useless.
How many people can actually set which DNS servers they connect to? That's 99.999% done by people's ISPs, who all in most likelihood use the 13 root servers.
So while a few people that use alternate DNS networks may be able to connect, the rest of the world would effectively go dark.
The other thing is that with all TLDs being administered as they are, alternate DNS services rely on the 13 root servers to get their DNS records anyways. So any future DNS is hosed, and any DNS changes are hosed. DNS records that did not change would still continue to work. If anything shut down the 13 roots, then these services would pretty much become drown in traffic overnight as word spread and people switched over to use them. That might actually be a good thing!
It would be nice if things were different, but I just don't see the powers that be wanting to relinquish control. (Does anyone have any info there? A number of years ago this was a hot issue. I do not know if there were any changes made.)
