Hello networkers.
Are you guys interested to filter the whole facebook segment at your company or at home?
Are you guys interested to filter the whole facebook segment at your company or at home?
Do you want to re-route or block facebook traffic at L3 level?
In case you have plenty of free time and willing to make a little bit of research you will find out that Facebook inc. is currently using 3 public AS world wide only:
AS 32934
AS 54115
AS 63293
AS 54115
AS 63293
(I used this url to validate public AS list: http://bgp.potaroo.net/cidr/autnums.html )
Anyways, within this ranges they have bunch of public network segments obviously. I worked one by one to bring you here the supernets matching ALL Facebook inc. segments.
Here we go:
31.13.64.0/18
31.13.24.0/21
45.64.40.0/22
66.220.144.0/20
