I think this is the first time I have seen the .int tld used.

[diggan]

It isn't super popular, no. I think the requirements are pretty strict if I remember correctly (edit: https://www.iana.org/domains/int/policy).

I think esa.int is probably one of the more popular .int domains on HN: https://news.ycombinator.com/from?site=esa.int

Other notable .int domains:

• World Health Organization - https://who.int

• NATO - https://nato.int

• Council of Europe - https://coe.int

• Mercosur - https://mercosur.int

• African Union - https://au.int

• EFTA - https://efta.int

In meteorology, you also have ecmwf.int (the European Center for Medium-Range Weather Forecasts).

It would have been better if the requirements also included the domain name had to start with a letter between I and N (inclusive).

But I guess this is what you get when these things get away from technologists.

interpol.int also comes to mind.

[rsynnott]

Probably the most appropriate one. The ESA is not quite part of the EU and has non-EU member states (including _Canada_), so .eu would be inappropriate (the EU is itself a member of ESA, but most EU member states are also members in their own right.)

The joke goes that thanx to Trump, Canada might actually join the EU.
