AS200

AS200 is an early, low-number autonomous system registered under ARIN to Level 3 Parent, LLC, the registry handle (LPL-141) for the former Level 3 Communications backbone now owned by Lumen Technologies, Inc. CenturyLink acquired Level 3 in November 2017 and rebranded the combined company to Lumen in September 2020, so AS200's WHOIS still carries the legacy name CENTURYLINK-LEGACY-LVLT-200 while contacts route to lumen.com. The key triage point is that AS200 is not Lumen's operational backbone — that role belongs to AS3356, the heavily peered global transit ASN — and AS200 itself behaves as a legacy/administrative number with minimal routing activity. Routing sources disagree slightly on its live state: bgp.he.net observes three IPv4 prefixes (190.13.114.0/23, 190.13.115.0/24, 190.107.216.0/24) that geolocate to Argentina and are associated with Lima Video Cable S.A. (Cabletel, AS52339), while bgp.tools and IPInfo describe AS200 as a stub AS not currently present in the global table — a discrepancy consistent with intermittent or recently-withdrawn announcements. All three observed prefixes are flagged RPKI Originated Invalid and IRR Parent Invalid (origin mismatch), and bgp.he.net flags bogon announcements, but these reflect legacy/customer misconfiguration rather than any documented malicious activity. AS200 is absent from Spamhaus ASN-DROP (confirmed via live JSON fetch), and no notable public abuse signal was found across AbuseIPDB, CleanTalk, Qrator Radar, or NANOG archives as of 2026-06-19. The only documented BGP incident in the Level 3 family — the November 2017 route leak — involved AS3356, not AS200.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-19 — absent from Spamhaus ASN-DROP (live JSON fetch confirmed), and nothing on AbuseIPDB, CleanTalk, Qrator Radar, or NANOG archives. Historical RPKI-invalid/bogon flags reflect legacy misconfiguration, not documented abuse. The Nov 2017 Level 3 route leak involved AS3356, not AS200

Network & routing

Network type

legacy/administrative ASN within the Lumen/Level 3 family; NOT the operational backbone (that is AS3356, a Tier 1 transit-free network). AS200 carries minimal routing activity [Confirmed] — bgp.he.net/AS200, peeringdb.com/asn/200, bgp.tools/as/200

Size

low-activity — bgp.he.net observes 3 IPv4 prefixes / 0 IPv6; bgp.tools and IPInfo report it as a stub AS not currently in the global table. AS rank and customer cone not published by bgp.tools [Likely] — bgp.he.net/AS200, ipinfo.io/AS200, bgp.tools/as/200

Routing/peering

1 observed BGP peer (AS52339, Lima Video Cable) [Likely]; upstreams not listed in any source [Unknown]. PeeringDB records AS200 as Open peering. Lumen's published settlement-free policy (peering@lumen.com) sets selective volume/RPKI requirements applying to Lumen ASNs

[Confirmed for PeeringDB/policy] — bgp.he.net/AS200, peeringdb.com/asn/200, lumen.com/en-us/about/legal/peering-policy.html

RPKI

all 3 announced IPv4 prefixes are RPKI Originated Invalid (0 valid ROAs) and IRR Parent Invalid (origin mismatch); RPKI-ROA contact RPKIR-ARIN (rpki-roa@lumen.com) registered 2024-06-17 [Confirmed] — bgp.he.net/AS200, rdap.arin.net/registry/autnum/200

Notable usage

Level 3/Lumen historically delivered content for Netflix and Apple and ran a CDN (acquired from Savvis, 2006); the operational backbone is AS3356. AS200 itself is a legacy number carrying minimal/dormant routing; bgp.he.net flags bogon announcements [Confirmed for backbone history; Likely for AS200 dormancy] — en.wikipedia.org/wiki/Level_3_Communications, bgp.he.net/AS200

Related ASNs

AS3356 (Lumen/Level 3 operational backbone); Level 3 holds a contiguous block of early low-number ASNs (AS199–203, etc.) [Confirmed for AS3356; Likely for the broader block] — bgp.tools/as/200, peeringdb.com/asn/199

IPv4 prefixes

190.13.114.0/23, 190.13.115.0/24, 190.107.216.0/24 — geolocate to Argentina, associated with Lima Video Cable S.A. (Cabletel, AS52339) [Confirmed for prefix list; Likely for association] — bgp.he.net/AS200

Analyst note

Encountered as an early/legacy ASN whose WHOIS resolves to Level 3/Lumen but whose live announcements (when present) are Argentine customer prefixes via AS52339. Routing sources disagree on whether it is currently in the global table; treated as low-activity/intermittent. Allocated date taken strictly from the autnum top-level registration event, not from the nested entity/POC dates (which were decoys).
