Internationalized Domain Names


#1

Is there going to be support for that?


Support domains Punycode
Support for new gTLDs such as .BANK
Do you support OpenNIC top level domains?
#2

If anything, all the support you should need should be in the client, to automatically perform the punycode (xn–) transformation.


#3

We’re still deciding whether we can include this for launch. The answer is probably no, because there are some tricky issues that need to be figured out, particularly with homoglyphs. We would like to support them eventually.


#4

Ah, but that would be a policy decision on the server side. At launch, you could return an error document saying “name not allowed” etc.


#5

Only need support for the danish æøå letters :smile:


#6

I am also very interested in Internationalized Domain Names support.

Please add them as soon as possible ;).

@Spambuster

Then, what about Swedish letters? And German letters? :slight_smile:

I live in France, where we have another set of accented letters. You don’t need to go very far before the need increases almost logarithmic.

The world grew so much with the global adoption of the Internet. :wink:

@Biker: I think @Spambuster was just joking around. :wink:


#9

That’s how I read his message as well. I’ve added a few smilies to indicate that I was in the same mood.


#10

They should get it too :smile:


#11

My brazilian domain haven’t accents, just http://vitree.com.br running with Node.js Angular.js MEAN.io application.

It has support to TLS digital certificated?

If not, how long to be released?


#12

That’s not an internationalized domain name (IDN).

IDN: https://en.wikipedia.org/wiki/Internationalized_domain_name
Punycode: https://en.wikipedia.org/wiki/Punycode


#13

@fernandosantucci, as @NOYB says, that’s a different issue and not a problem for you. :smile:

Aqui se fala dos nomes de domínio internacionalizados (ou seja, com acentuação gráfica ou conjunto de caracteres não-ASCII), e não dos internacionais (tais como .br).


#14

I think thаt IDNs will not be implemented for а while, for obvious reаsons thаt you cаn eаsily present а domаin thаt looks like one а bank has аnd get а certificаte issued.

I аm quite confident thаt you hаven’t noticed that аll of my A’s in the previous аnd this sentence аre Cyrillic A’s.

Compаrison

  • Common A: а
  • Cyrillic A: а






Got you аgаin, this is a reаl compаrison between the common A аnd the Cyrillic A.
Common: a
Cyrillic: а

By the way, what are the issues exactly? I can understand there can be issues with the client (inputing the '+e é instead of the native é). But if I input it in the xn–* form (as I still have to do for most mail clients anyway…), it should look like just like a regular domain name to the CA.


#16

As @jsha previously pointed out the main concern is homoglyphs, characters that visually look alike but have different code points. This basically means somebody might be able to create a domain name that looks exactly like a high-value domain name but if you did a string comparison between the two domains they wouldn’t match and could point to two different websites.

This means we could accidentally issue a certificate for a domain that looks like google.com even though that name is already part of a high-value anti-phishing blacklist.

(Wikipedia has a pretty good article on duplicate unicode characters, which are part of the concern, here – https://en.wikipedia.org/wiki/Duplicate_characters_in_Unicode)


#17

This is possibly a stupid question, but do the newer TLD’s such as .app .docs .beer etc fall under “international” domains as well? Or will the be supported at launch? I have a few domains that utilize some of the new TLDs that were introduced this year.

Sorry, I just saw the reply here Do You Support Free Domains stating they should be supported at launch.


Support for new gTLDs such as .BANK
#18

@Taubin, that’s right! There’s a distinction between international domain names (fully supported) and internationalized domain names (not currently supported). The international domain names are those under a foreign-based country-code top-level domain (like .de, .ru, .za, .uk) and the internationalized domain names are those that contain a non-ASCII character (like παράδειγμα.com or 例子.com).


#19

@Taubin

Also a couple of good Wikipedia page links that may assist with clarifying the Internationalized Domain Names (IDN) distinction are provided earlier in this thread.


#20

What about internationalized domain names under sensible ccTLDs which do not allow homoglyphs?

Like it is not possible to register аbc.de or аbc.fi (аbc.de or аbc.fi) containing a Cyrillic a as these ccTLDs accept only a limited set of accented letters and such but not symbols, other scripts or anything like that.

For this kind of ccTLDs there are no need for extra homoglyph tests, as registry authorities have prevented them altogether.
