AS516

AS516 is a legacy autonomous system number registered under ARIN in September 1989 to "Eastman Kodak Boston Technology Center" (registry handle EKBTC), an internal facility of the Eastman Kodak Company photography-and-imaging corporation. The registry record's top-level registration event dates to 1989-09-06, with a last-changed event of 1996-06-10; both are first-party ARIN RDAP autnum facts, not entity-level decoys. The ASN is dormant on the public Internet today: RIPEstat reports zero announced IPv4 and zero announced IPv6 prefixes, zero RIS peer visibility (0 of 327 IPv4 peers, 0 of 321 IPv6 peers), and zero observed BGP neighbours. CAIDA AS Rank corroborates this, placing AS516 at rank 79,459 with a customer cone limited to itself (1 ASN, 0 prefixes, 0 addresses) and zero customer/peer/provider relationships. There is no PeeringDB record for AS516 (peeringdb.com/asn/516 returns 404), and Kodak's current corporate website contains no reference to a Boston Technology Center, network operations, or peering infrastructure — the facility appears defunct with no present-day public-facing footprint. The administrative/technical/abuse point of contact (Richard Messinger, Eastman Kodak Research Labs, Rochester NY) has been flagged by ARIN as unvalidated since 2010-06-20, consistent with an orphaned legacy allocation. No AS516-specific abuse, hijack, or blocklist signal was found in Spamhaus ASN-DROP, NANOG archives, or general threat-intelligence searches as of 2026-07-10; a June 2026 Kodak corporate data breach (ShinyHunters) is an unrelated application-layer incident with no disclosed ASN/network tie and is not attributed here.

Operator

Eastman Kodak Boston Technology Center (ARIN registrant org EKBTC); parent corporate entity is Eastman Kodak Company [Confirmed] — https://rdap.arin.net/registry/autnum/516, https://www.kodak.com/en/company/home/

Country / RIR

US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/516

Allocated

1989-09-06 (ARIN RDAP top-level autnum registration event); last changed 1996-06-10 [Confirmed] — https://rdap.arin.net/registry/autnum/516 (top-level events[], corroborated independently by three research angles)

Org status

ARIN registry status "active" (record not reclaimed), but the listed POC (Richard Messinger) has been unvalidated by ARIN since 2010-06-20 and the ASN shows zero live routing activity — consistent with a dormant/orphaned legacy allocation rather than an actively managed network

[Confirmed] — https://rdap.arin.net/registry/autnum/516

Website

no dedicated operator/network site exists for the Boston Technology Center; Kodak's current corporate site (kodak.com) makes no reference to this facility [Confirmed] — https://www.kodak.com/en/company/home/

Security/abuse context (NEUTRAL, DATED)

no notable public abuse, hijack, or blocklist signal found as of 2026-07-10 in Spamhaus ASN-DROP, NANOG mailing-list archives, or general BGP-hijack/threat-intel searches; consistent with a dormant, unrouted legacy allocation

Network & routing

Network type

legacy enterprise/end-user ASN, currently inactive/unrouted (not transit or content) [Confirmed] — https://bgp.he.net/AS516, https://stat.ripe.net/AS516

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses, 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — https://stat.ripe.net/AS516, https://asrank.caida.org/asns/516

Routing/peering

NOT announced — 0/327 v4 and 0/321 v6 RIS peers seeing it; CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB listing (404) and no published peering policy located [Confirmed] — https://stat.ripe.net/AS516, https://www.peeringdb.com/asn/516

RPKI

not assessable — AS516 announces no prefixes, so RIPEstat rpki-validation was skipped (requires a prefix parameter) [Confirmed] — https://stat.ripe.net/AS516

Notable usage

historical/administrative only — registered 1989 as an internal Kodak facility ASN; no evidence of current operational use, public-facing services, or BGP announcements beyond the registry record itself [Likely] — https://rdap.arin.net/registry/autnum/516

Related ASNs

none — ARIN's organisation-to-ASN listing for registrant org handle EKBTC returns exactly one autnum, AS516 (KODAK-BTC), so no sibling ASN is registered under the Boston Technology Center org record; no separate ARIN org record for the parent Eastman Kodak Company surfaced alongside it

[Confirmed for org EKBTC] — https://whois.arin.net/rest/org/EKBTC/asns.json (queried 2026-07-28)

Analyst note

dormant 1989 legacy ASN with a solid first-party ARIN registration date, zero live routing footprint across every routing source consulted (RIPEstat, CAIDA, bgp.he.net), and no PeeringDB or abuse signal. A June 2026 Kodak corporate breach (ShinyHunters, ~2.2M PII records) is unrelated at the network/ASN level and is deliberately not attributed to AS516.
