Frequently Asked Questions

Which country has the most spam sources?: In the snapshot of 2026-10-11, China has the most spam sources in absolute terms (201 flagged networks), followed by the United States (163). Per million allocated IPv4 addresses, India ranks first (1.76). Absolute counts mostly follow where large hosting networks are; the rate shows how much of a country's address space is involved.
What is a spam source?: Sources of email spam.
How are spam sources counted on this map?: Flagged addresses are counted as /24 networks: all listed addresses within one /24 count once, and larger ranges count as a single /24. A network listed in several categories is counted once, in the most specific category (C2 before phishing, botnet, brute force, spam, scanner and other malicious activity), so the categories add up to the country total. Address space that is not announced in BGP is left out.
How often is the data updated?: Once a day. Every snapshot uses the listings that are active on that day, aggregated from multiple external and internal threat intelligence sources; listings that are no longer reported drop out of the next snapshot.
