This question has always been bugging me. I know there are different domains endings... .net, .com, .tv, .org, .gov
However, why is only the US Government that owns the .gov domain
Why do the other governments have to use the .gov.il , .gov.uk
How come its the US that owns this .gov address?

At the time I don't think they realised there was a world outside the US

I would say the first paragraph sums up your question. I don't think they plainly say it, but DARPA is part of the US Military.

You can google for 'history of dns' if you want to know more.

US gets to omit the country name because the Internet was invented there. Similarly, postage stamps were invented in the UK & UK is the only country in the world that doesn't put its name on its stamps.

or maybe they never intended the internet to spread around the world?

We Americans know there are other countries and you foreigners are just jealous
good thing you said "at the time"

I don't think that anybody doubts that ARPANET and INTERNET like UNIX and most of the stuff related to Computers started in USA but I think amosf's answer, even by omitting the "at the time" contains some truth.
Look at the first two words of your reply: "We Americans".
I don't know about you but in Greek schools they teach us that America is a continent and contains many countries including the USA...
The last time I checked a map I've seen Brazil, Mexico, Argentina, Canada, Chile, etc being part of America, when you by saying "We Americans" definitely are referring to the people from the United States of America.

They teach that here too, but what do you expect us to call ourselves?

oh yeah America is two continents

We in the US learned that that there is a North America and South America. Argentina, Brazil, Colombia, and Chile would be S. America. US, Canada, Mexico, Panama, etc would be N. America.

To say you are American, to me, would imply that you are from the US. If you were from somewhere else in the N or S American contenent you would say you are Mexican or Brazilian or Canadian, or whatever.

When I first read your post, I felt really ashamed of myself. For the first time in my life I've heard that America is two continents. So I tried a little research, and look what I've found in wikipedia:
For me America is still one continent... (and 1 region)
I'm pretty sure we both learned something today

thanks!!
finally got an answer to this

In most countries (including Greece) when we refer to Americans, most of the time we mean you, it 's just a little ironic, when someone says something like "you haven't realized there is a world outside the US", to start your reply with "We Americans", since although this is how you define yourselves (Americans= people of USA), it's still a part of what you are "accused" of, and as far as I know some people in Latin America find this irritating since they believe they are also Americans. Especially when you say America and you refer to USA. I don't have any problem with this (why should i?), it just looked funny and I mentioned it.

P.S.1 In Greece we learn that there is a North America (US, Canada) , a Central America (from Mexico to Panama) and a South America, but those are all considered as one continent.

P.S.2 Sorry for keeping this off topic
