No. It is still the WhatsApp server making the request to your website - so you only see the server's IP.

Facebook makes one request and then caches the result. Other servers may not store the result.

[Here's how signal does it](https://hub.packtpub.com/signal-introduces-optional-link-pre...).

TL;DR, the app establishes a TLS connection directly between your phone and the site, but routes it through a proxy on Signal's server, thereby hiding your IP without being able to view the URL. I imagine Whatsapp works in a similar fashion

Doesn't that break end-to-end encryption?
