Spam Activity in Hosting Networks (ASNs)
June 1,2023 - August 31,2023

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 show the twenty hosting networks with the highest numbers of reports of spammed content or spambots. Complete lists of ASNs reported for the period can be downloaded in CSV format from the Records page.

To allow comparison of large and small Hosting Networks (ASNs), we also rank Hosting Networks based on a metric, hosting network spam score, which is calculated by dividing the number of spammed content or spambot hosts reported against an ASN by the number of routable IPv4 addresses allocated to that ASN.

Hosting (ASN) Spam Score = (number of spammed content or spambot hosts /IP Addresses in ASN) * 10,000

In the table below, we show the top 20 hosting operators based on spam score.

Ranking of Hosting Networks (ASNs) by Spam Attack Score (June to August 2023)
