AS676

AS676 is a live, actively routed ASN registered to the United Nations Development Programme (UNDP) via LACNIC, announcing 10 IPv4 prefixes (4,096 addresses, 200.16.96.0/20 and sub-/24s) from Buenos Aires with no notable public abuse signal.

The LACNIC RDAP record lists the registrant as UNDP, but several independent signals point to the network's day-to-day operator being Argentina's Ministry of Foreign Affairs (MRECIC/Cancillería) rather than UNDP directly: the registrant postal address matches MRECIC's headquarters (Esmeralda 1212, Buenos Aires), the technical/abuse contact is noc-ar@mrecic.gov.ar, and bgp.tools tags the announced space to the Ministry by name. This is consistent with a 1990s-era UNDP-sponsored connectivity allocation whose registrant name was never updated as operational control shifted.

The RIR registration event on file (LACNIC RDAP autnum, first-party) is 1990-05-23, last changed 2000-05-30. A separate live RDAP fetch attempt via rdap.org failed outright (HTTP 406), but this is a tooling failure on one angle, not a refutation of the date independently confirmed by two other angles reading the LACNIC record directly.

Routing posture is small and stable: CAIDA AS rank 21856, customer cone of one ASN (itself), AS-degree of 2 provider relationships and 0 peers/customers, with 325/325 RIS peers seeing its IPv4 announcements and zero IPv6 presence. No PeeringDB listing exists for AS676.

Exposure

Small, single-country announcement footprint (4,096 IPv4 addresses, no IPv6); no PeeringDB listing and no public peering policy found.

Abuse signal

Not listed on Spamhaus ASN-DROP (checked live, 2026-07-18); no NANOG/seclists archive mentions found.

RPKI

Not assessed this pass — RIPEstat's rpki-validation endpoint requires a --prefix argument that was not supplied.

Unrelated incident

A March 2024 UNDP-organization data-extortion incident (Copenhagen/UN City HR data) is documented but is organizationally and geographically distinct from AS676's Argentina-registered space; do not attribute it to this ASN.

Country / RIR

AR; legacy ARIN-administered block, abuse/routing authority now LACNIC [Confirmed] — https://stat.ripe.net/AS676

Allocated

1990-05-23 (LACNIC RDAP top-level registration event); last-changed 2000-05-30 [Confirmed — corroborated independently by two angles reading the LACNIC autnum record; a third angle's separate rdap.org fetch failed with HTTP 406 and is not a refutation] — https://rdap.lacnic.net/rdap/autnum/676

Website

Unknown — undp.org blocks automated fetch (HTTP 403); noc.undp.org is a retired redirect stub with no AS676 content; cancilleria.gob.ar has no dedicated network/IR page [Unknown] — https://noc.undp.org/, https://www.undp.org/

Org status

Active, DIRECT ALLOCATION per LACNIC RDAP [Confirmed] — https://rdap.lacnic.net/rdap/autnum/676

Security/abuse context

no notable public abuse signal as of 2026-07-18; not on Spamhaus ASN-DROP; no NANOG/seclists mentions found

Network & routing

Network type

government/institutional end-user network, single-country (AR); not an ISP, IXP, or transit network [Likely] — https://ipinfo.io/AS676, https://bgp.tools/as/676

Size

10 IPv4 prefixes, 4,096 addresses within 200.16.96.0/20 and component /24s; 0 IPv6 prefixes [Confirmed] — https://stat.ripe.net/AS676

Routing/peering

CAIDA AS-degree 2 provider / 0 peer / 0 customer; upstreams AS3549 (Lumen) and AS11014 (Metrotel, AR); customer cone = itself only; no PeeringDB listing (404) [Confirmed for CAIDA/RIPEstat figures; Likely for the named upstream carriers] — https://asrank.caida.org/asns/676, https://stat.ripe.net/AS676, https://bgp.tools/as/676

RPKI

not assessed this pass — RIPEstat rpki-validation requires a --prefix argument, none supplied [Unknown] — (no citation, tooling gap)

ASN / holder

AS676, "United Nations Development Programme" (RIR registrant of record) [Confirmed] — https://stat.ripe.net/AS676, https://rdap.lacnic.net/rdap/autnum/676

Operational discrepancy

registrant name reads UNDP, but the RDAP postal address, abuse-contact domain (mrecic.gov.ar), and bgp.tools tagging all point to Argentina's Ministry of Foreign Affairs as the actual day-to-day operator
