Spam Activity: Hosting Networks (ASNs): Quarter over Quarter June 1,2024 - August 31,2024
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 March 1, 2024 - May 31, 2024 period to the ranking for the June 1,2024 - August 31,2024 period.
