Level 3 Parent, LLC

LEVEL 3 PARENT, LLC appears in public filings as part of the Lumen Technologies corporate structure and is referenced as the direct parent of Level 3 Financing, Inc., providing guarantees for multiple debt issuances. Public network directories also list it as the organization behind long-running “Level 3” autonomous systems tied to backbone/transit operations in the United States.

Multiple BGP datasets attribute major ASNs to Level 3 Parent, LLC, including AS3356 (widely visible as “LEVEL3”) and other legacy Level 3/CenturyLink-related entries. PeeringDB associates the organization with AS199 (CENTURYLINK-LEGACY-LVLT-199), and ARIN whois records show allocations registered to the same org identifier; overall, the infrastructure footprint is best observed via these ASNs and their routed prefixes.

Standalone end-user review coverage for the legal entity name is sparse, but broader “Lumen/Level3” service feedback online trends negative, with recurring complaints about support responsiveness and incident handling in community threads; this pulls the reputation signal down. At the same time, some risk-scoring datasets classify traffic from this ISP as low fraud risk, which is a separate, more favorable indicator.
