About this network

ScanMalware.com performs public URL scans, then maps each scanned host to its current ASN ownership and BGP routing context. AS209's footprint above is built from those scans plus live BGP data: which IP prefixes the AS announces, which networks transit it, and which countries it operates from.

If you're investigating a suspicious site hosted on AS209, this profile lets you pivot from a single host to the broader network — for example to spot whether the same operator is hosting other suspicious content, or whether the AS has a history of compromised infrastructure.
