Instagram subdomain "z-p4", what is it used for?

I was on instagram earlier, and like most people, I will sometimes get random follow requests from fake looking accounts. The profile pic was porn model and the message was like "Come follow me on my private page to see more of me" or something.

Every now and then, I click these links and see where it leads out of curiosity. When you click this one, it just sends you to this URL:https://z-p4.www.instagram.com/

And it shows my normal instagram feed as always. I googled the subdomain but couldn't find much info on it, other than it is definitely exclusively tied to facebook/instagram.

Does anyone know why this exists and what the subdomain was originally designed for?
