Spam Activity in Hosting Networks (ASNs) September 1, 2023 - November 30, 2023

To see where spammed content or spambots were being hosted, we collected the IP addresses that spam domains were resolving to when spam activity was detected and added to a threat or block list. We then identified the ASN where the IP prefix containing the IP address was allocated. This number identifies the hosting network where spammed content or a spambot was reported.

In the table below, we compare the ranking of Hosting Networks (ASNs) for the June 1, 2023 - August 31, 2023 period to the ranking for the September 1,2023 - November 30,2023 period.
