What fun
origonally TLDs were assigned by the people who used them hence:-
.acc .gov .mil
As more people got in on the act we got:-
.net .com .org
Then some British Accedemics started having problems claiming expenses for trips to California so, sadly, they started managing thier own TLD and reflected the US structure within the "uk" domain so we get the wierd looking:-
.ac.uk , .gov.uk .co.uk etc.
A short time later there was a "me too" clamour of countries insisting on thier own TLDs (even though in most of these countries academics could still claim a nice pile of expenses for a trip to California ).
The internet powers that were headed of a massive bun fight among all the foriegners over who got what name by saying they had to use thier ISO country code. (The results of a previous massive bun fight).
However the ISO country code for "The United kingdom of Great Britain and Northern Ireland" is not TUKoGBaNI or even UK but GB.
"Great Britain" being the geographical description for the large island shared by England, Scotland and Wales but excluding other Islands comprising the British Isles such as Ireland, Skye, Shetland, Wight, Man etc. so the TLD actualy only covers 80% of British territory.
We can resolve this anomily, and, the problem of the orphaned "su" TLD if the various other British lsles followed the the Ilse of Man's example and applied for thier own TLD.
I think the people of South Uist would gladly welcome the refugee URLs from the former Soviet Union.
