First we need to understand what is an IDN.ascii, and what is IDN.idn.
Let's use an IDN.ccTLD domain ä¸*å½.cn [China.cn] for example.
User <-- [ä¸*å½.cn]--- (Software/Browser) --- [xn--fiqs8s.cn] --> Root Server
xn--fiqs8s.cn is no different from any ASCII domains like LOANS.cn in the registry, they are all ASCII domains. But why we call xn--fiqs8s.cn an IDN domain?
Because the browser makes it look like an Chinese (Unicode) domain. Whenever the software/browser sees a domain start with "XN--", it will apply "Punycode Scheme" formular to the ASCII script after "hyphen hyphen" and translate it into Unicode character(s). So in this case xn--fiqs8s.cn looks like ä¸*å½.cn to the user.
And vice versa, when the user types ä¸*å½.cn URL to the browser, the browser translates it to xn--fiqs8s.cn then sends it the Root server.
So, is IDN.ascii usable? valuable? Absolutely, 100% just like any other ASCII domains.
Now IDN.idn.
A domain we see is always with an extention like .cn, and we know xn--fiqs8s.cn is to be resolved at the root server in China.
Many people in many different countries ask, if we can make the domain part look like Chinese, why don't we also make its extention look like Chinese? like ä¸*å½.ä¸*å½
That's how the idea IDN.idn came from. Of course, it's very easy to achieve this.
1) If when the browser translates the domain (Punycode), it's also programmed to translate the extention at the same time, it's done. Or
2) ICANN can help China create a new Top Level Domain (ä¸*å½) in the Global root server, and the new domain (ä¸*å½) will be .XN--FIQS8S. So, ä¸*å½.ä¸*å½ will be resoved as xn--fiqs8s.XN--FIQS8S in ICANN's Root server.
User <-- [ä¸*å½.ä¸*å½]--- (Browser) --- [xn--fiqs8s.XN--FIQS8S] -> Root Server
Will they work? Absolutely, the project is now under discussion at ICANN.
IDN.ascii domains will become mainstream soon because they are seriously in demand in all non-English speaking countries. But if you want to know if IDN.idn is a good idea, my opinion is NO. I will try to present my argument later.
----------
Why is IDN.idn not needed?
Before we continue, I must emphesize again that IDN.com or IDN.cn or IDN.jp is urgently needed. Don't confuse IDN domain name with its extention.
Now try these:
1) If we have only one Top Level Domain in the world, do we need extentions for domains? Of course we don't, we can just use the name without extention.
2) If we have only 2 TLDs, we can make it easy to distinguish between them by grouping them into two TLDs .1 and .2, like LOANS.1 and LOANS.2.
3) Now we have a few gTLDs and more than two hundred ccTLDs, it's certainly much better to use 2 letters or 3 letters for extentions than using numbers because letters can have better representation.
From
#1,
#2 and
#3, we can see the basic characteristic of domain extention:
A) Extentions are used to categorize domains, so that domains can be sent to the right root server to be resolved.
B) Extentions should be as short, simple and meaningful as possible.
From A) and B) we can conclude that IDN.com, IDN.cn, IDN.jp... are in their best form now, and ICANN should start their full deployment.
Just look at this domain
http://www.åå¹³.com it's so beautiful!
And it also gets me some income every month, because so many people love PEACE.
BUT wait a minute...
Some people in non-English speaking countries suggest we should translate the extentions into their local scripts as well, with these reason:
I) They don't have to shift the key to type the Latin extention.
II) They feel proud to see the extention in their own language.
I do know why I) and II) because I am a Chinese and I speak and write the language. But I can't find a sufficient reason to create a new "XN--" TLD in the root to satisfy our unnecessary wish.
I) Microsoft just need spending 15 minutes to modify the browser to allowed us to enter .cn or .com during the Chinese input mode without shifting.
II) Chinese are very familiar with Latin letters, they learn Pinyin in their elementary school and Latin letters are part of their life. When China sent its astronauts to the Space, all Chinese should feel proud to see the word ä¸*å½ printed on the Spaceship. But we should not print ä¸*å½ all over the places like washroom, bedroom, diningroom ... to make us proud, and certainly not at the domain extention where the simpler is the best.
If .cn, you only need 2 keystrokes. if .ä¸*å½, you need 9 strokes by Pinyin Input Method (zhongguo + "Enter"). (9 - 2 = 7 strokes more)
Suppose China will have 500M netizens in the near future, and each net user enter average 10 domains a day.
500M x 7 x 10 x 365 = 12,775,000M = 12.775 Trillion strokes per year.
What a waste of human energy, not to mention if 1/3 of the users have IQ like me and input (zhongguo + "Enter") wrong one in every 3 entries .
Yes, some people now would say they have no problem inputing .ä¸*å½ and that they like .ä¸*å½ better, but when put it into practical use, the truth "simpler is better" will prevail, people will prefer .cn.
As for IDN.com, "com" has nothing to imply pride. There will be no one would feel proud to use åå¹³.å
¬å¸ or åå¹³.åä¸. So, it's better for IDN.com to remain IDN.com, the king of all.
During this confused time of looking for names to map "com" to, I would like to quote a word of wisdom from China's "Art of War".
"以ä¸ååºä¸å" (No change is the best change)
(This is just my personal opinion)
