In the UK, commercial sites end in .co.uk, and Academic Community sites in
.ac.uk. It seems that many English-speaking countries use the same convention.
 
In France, most universities are .u-xxx.fr or .univ-xxx.fr, but those that
were on the net long ago often have class A names. For instance, in Universite
de Paris-Sud, most labs use @<lab-name>.u-psud.fr, but the Computing Science
lab is plain  @lri.fr. As usual, the French dislike standards :-)
 
In Germany, most (all?) universities are uni-xxx.de, or tu-xxx.de for
technical universities.
 
To answer your question, most countries have some kind of organization but
there is no international standard (beyond top-level domains, of course).
