LEVEL3
AS3356 is an Autonomous System — a group of IP networks managed under a single routing policy — operated by LEVEL3, announcing routes from US. ScanMalware.com has recorded 175 public scans of 159 distinct URLs hosted on this network, the earliest from 2025-10-03 and the most recent from 2026-06-15.
In current BGP routing data, AS3356 announces 55,853 IPv4 prefixes and 4,241 IPv6 prefixes, and is reached through 6 observed upstream providers. A network's routing footprint and transit relationships are useful context for judging whether a hosted site sits on established infrastructure or on a network with a pattern of abuse.

How ScanMalware builds this profile
ScanMalware.com performs public URL scans with a real headless browser, then maps each scanned host to its current ASN ownership and BGP routing context. This profile is built from those scans plus live routing data — the IP prefixes AS3356 announces, the networks that transit it, and the country it operates from — letting you pivot from one suspicious host to the wider network it sits on.
