That list is just for .com domains. This Wikipedia entry lists old .com, .org, .edu and .net domains: http://en.wikipedia.org/wiki/List_of_the_oldest_currently_re...

Also, I found it amusing how much overlap there is between the 50 oldest .edu domains and the US News list of top CS grad programs: http://grad-schools.usnews.rankingsandreviews.com/best-gradu...

Universities were heavily involved in the creation of the internet/ARPANET, and IIRC, the University of Utah was the third host on the internet (in 1969 or 1970), so the list probably just omits the non-dot-com domain names.

.EDU was created at the same time as .COM, in January 1985. See: http://en.wikipedia.org/wiki/.edu#History

Before then, universities that were on the ARPANET (those with research funded by the Defense Department) were under the .ARPA domain.

None, of course, will appear before the domain system was setup. These are for TLDs only. Arpanet came before, as well as other competing networking systems, and it was only the transition to a domain system that this history makes sense. See RFC 799 written in September 1981.

It's filtered to only contain .com. The first .se domain was registered sometime in 1986, which would definitely place it pretty high on that list.
