Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection (and a whole bunch of Unifi/Ubiquiti/Ubtn links).

Posted by jpluimers on 2019/01/21

Seems my interest in Ubiquiti needs more research: [WayBackLinus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection.

Hopefully by now I’ve time to re-design the WiFi coverage in the house and invest in a few of those access points.


Splitting 5Ghz and 2.4Ghz SSIDs: two ways (I think the second is cleaner)

  1. Either have one WLAN group with a set of SSIDs, then in each access point disable the 2.4Ghz SSID on the 5GHz radio, and disable the 5Ghz SSID on the 2.4Ghz radio
  2. Have different WLAN groups with an SSID (or set of SSIDs) for each frequency, then in each access point select the appropriate group for each radio

For both the first and second one, you need to configure under “Config” -> “WLANs”.

For the second one, you can clone from the first, then change the SSID names.

Strange MAC addresses starting FA:8F:CA without OUI in your network? They are Locally Administered Addresses and likely from Google.

Posted by jpluimers on 2019/01/07

A while ago, I write about Locally Administered Addresses: a few series of MAC addresses you can use on your local network: MAC address ranges safe for testing purposes (Locally Administered Address).

A while ago, I found ones in my network and ones in my WiFi SSID survey starting with FA:8F:CA. They did not show up in the Wireshark · OUI Lookup Tool nor their manufacturer database.

But with bit 7 turned off they start with F8:8F:CA which does show up as “F8:8F:CA Google, Inc.”

They appear to be Google devices, in my case Google ChromeCast ones, though they can also be Google Home ones.

Google does “magic” with networks, just look at a few of the links here:

Not sure when this happened but the CIDR list is no more [WayBack

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: 
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:
For any technical requests please contact us through the Support section of the portal: 
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:

Time to find an automated way to get the replacement list. Maybe the below helps (via [WayBackBlock facebook messenger and whatsApp on Dlink router – Super User)
