Whoa me too, in about 15 years of surfing the web I've never noticed any .int TLD. Not old enough for .arpa but this is cool. I would have not seen this without your pointing it out. Thanks for the life experience! ;) With mobile browsers these days most of the time the URL isn't even shown.. So I hope everyone can appreciate this

The European Union web page is europa.eu.int. That's the biggest one I can think of.

I do admit that one probably don't see that one a lot if you don't live in Europe.

You're a little out of date there, I'm afraid. They officially switched from europa.eu.int to europa.eu in May 2006, after the EU's successful campaign to get their own .eu TLD in 2005.

.arpa is used for reverse DNS lookups. The PTR record for the IPv4 address 1.2.3.4 is looked up at 4.3.2.1.in-addr.arpa.

And for enum lookups, e.g. [phone] becomes 8.7.6.5.5.5.5.1.e164.arpa.
