Some TLDs in PSL are not in IANA Root DB

[umairkhan-dev]

Sorry, this is more like me asking about why instead of an issue.

IANA has a list of TLDs at https://www.iana.org/domains/root/db and https://data.iana.org/TLD/tlds-alpha-by-domain.txt
I noticed that there are some TLDs in ICANN section of PSL that are not listed in IANA's list.

For Example.

1. ايران (xn--mgba3a4fra)
2. 澳门 (xn--mix082f)
3. پاكستان (xn--mgbai9a5eva00b)
4. السعودیة (xn--mgberp4a5d4a87g)
5. السعودیۃ (xn--mgbqly7c0a67fbc)
6. السعوديه (xn--mgbqly7cvafr)
7. سوريا (xn--mgbtf8fl)
8. 臺灣 (xn--nnx388a)
9. اليمن (xn--mgb2ddes)

... and some more.

Please, I am confused, why is that so.?

Thanks for the question @umairkhan-dev

Please see ICANN's ccTLD IDN Fast Track Specifically, look at the table, fourth column,
I believe, working from memory of the rationale we used at the time, was that many or most of the strings listed above may have been identified by ICANN as Desired Variants of delegated ccTLD IDNs and were defined at the time by the IANA/ICANN as part of their ccTLD notices. Since that time there has been more structure added to the process by ICANN and the IANA, but the strings remain in the PSL to avoid disruption to any of the affected communities. The respective authority for each ccTLD IDN may request their removal.

@dnsguru Thanks alot for your reply. Sorry, I am new to TLDs as developer and I am making a small tool to check if given address has proper TLD. So I got my primary list from IANA and then had an intro with PSL and got confused.

I have some more questions.

The desired variant string(s) are strings allocated to the requester. This does not mean that they will be delegated in the DNS root zone. They will be allocated to the requester in order to be reserved to the entitled manager for potential future delegation in the DNS root zone.

1. Above quoted as mentioned here.
   Is it safe to assume that the list provided by IANA (here) is final for the time being, and if a desired variant string makes way in DNS root zone, the IANA list will be updated.

2. There are some TLDs which work slightly different than how they should work.
   for example. *.bd (// bd : https://en.wikipedia.org/wiki/.bd). Asterisk (*) defines, I assume, that any sub-tld can be used with .bd, however .bd only allows the ones mentioned in their wiki page.

Appreciate the questions, as these all build documentation for future eyes and others who want to know more.

Wise to not treat it as static. IANA of course is most appropriate party to answer a question about the IANA list, but it is updated as time progresses and ccTLDs introduce IDN namespace (or new languages or variants). The most significant change was the namespace expansion from the 2012 nTLD round, and there are occasional changes in the ccTLD space.

There are some TLDs which work slightly different than how they should work.
for example. .bd (// bd : https://en.wikipedia.org/wiki/.bd). Asterisk () defines, I assume, that any sub-tld can be used with .bd, however .bd only allows the ones mentioned in their wiki page.

There likely may exist legacy entries in the PSL which may not be aligned to their current operations. TLD administrators are encouraged to review their entries and update them. Where volunteers in the community see a TLD needing to be updated, please encourage the respective TLD administrators to submit updates.

@dnsguru Lots of thanks for your reply. It did clear some confusions.
For now, I have nothing to ask more. But I'll bug you in case of more questions / confusions.
Thanks again.

@dnsguru I have another question. Pardon if i can not explain my question.

Commenting to this instead of opening a new issue.

Some TLDs in PSL are available for public registration and a few are not. Is there a common list like PSL that I can check.
E.g.
I can register a .com domain as its available for public registration, but I can not register .google domain even its in ICANN part of PSL but its registration is not publicly available.

This is not really something the PSL is there to contain. That said, you can typically find the policy for tlds on nic.[tld] Also, if a TLD identifies as a spec 13 in this list, there is a likelihood that it would be more like your .google example.

Should clarify... "this list" meant the json file from ICANN (not the PSL)

This is not really something the PSL is there to contain.

Sorry, I know that PSL is not meant for this. I referenced PSL to ask for something like this.

Thank you very much for your rapid response.
