[At-Large] DomainIncite : Is this why WhatsApp hates some TLDs but not others?

[Bill Jouris]

He complains that he couldn't get ICANN interested in the problem. It would be interesting to know just who at ICANN he was talking to.

That’s the picture that seems to be emerging from one new gTLD operator’s quest to discover why WhatsApp doesn’t recognize its TLD, and many others including major dot-brands, as valid."
....When most social media apps detect the user has inputted a URL or domain name, they automatically “linkify” it so it can be easily clicked or tapped without the need for copy/paste.

But when Rami Schwartz of new gTLD .tube discovered that .tube URLs sent via WhatsApp, said to have two billion users, were not being linkified, despite the TLD being delegated by ICANN almost eight years ago, he set out to find out why.

Schwartz compiled a spreadsheet (.xlsx) listing which gTLDs are recognized by WhatsApp and which are not and discovered a rough cut-off point in November 2015. TLDs delegated before then are linkified, those delegated after were not......This means that, for example, .microsoft domains linkify but .amazon and .apple domains do not; .asia domains linkify but .africa and .arab domains do not; .london works but .abudhabi doesn’t. Even .verisign missed the cut-off.

If WhatsApp users include a “www.” or “http://” then the app will linkify the domain, even if the specified TLD does not exist.

.....During the course of a discussion on the web site of the Public Suffix List — which maintains an open-source list of all TLDs and the levels at which names may be registered — it was discovered that the problem may be deeper rooted than the WhatsApp app.
It turns out a library in the Android operating system contains a hard-coded list of valid TLDs which hasn’t been updated since November 24, 2015"
