Not sure when this happened but the CIDR list is no more [WayBack] https://www.whatsapp.com/cidr.txt:
Dear partners, Please note that we have migrated the latest IP pools of WhatsApp to Facebook Mobile Partner Portal. Feel free to browse to the Settings page of the portal and download the latest WhatsApp IP pool: https://fb.me/mpp_support Further IP pool updates are also done through the portal and are no longer distributed via email or through WhatsApp web site. If you have not yet registered on the Mobile Partner Portal or have difficulties accessing it - please request access through the following form and we'll be happy to assist: https://fb.me/mpp_access For any technical requests please contact us through the Support section of the portal: https://fb.me/mpp_support WhatsApp team
In the past it was the place to get the CIDR so you could either block or allow WhatsApp traffic: [earlier WayBack]
It is still widely cited as way to regulate WhatsApp traffic, for instance at these places:
- [WayBack] Solved: Instand Messenger in Guest Network – Ubiquiti Networks Community
- [WayBack] Blocking WhatsApp in Mikrotik | Syed Jahanzaib Personal Blog to Share Knowledge !
Time to find an automated way to get the replacement list. Maybe the below helps (via [WayBack] Block facebook messenger and whatsApp on Dlink router – Super User)
