Unclassified APNIC
Summary
La Nación
enterprise legacy
LA NACION is the autonomous system of La Nación, the Buenos Aires daily newspaper and one of Argentina's largest news publishers. It is a single-prefix corporate network, not a service provider.
What it's used for
The routing evidence is about as unambiguous as this sweep gets. RIS sees exactly one announced IPv4 prefix, 200.80.156.0/24 (256 addresses), no IPv6, and one observed BGP neighbour. RDAP registers that /24 to an org literally named La Nacion, and the sampled reverse DNS on it resolves under LANACION.COM.AR (lan-156-5.LANACION.COM.AR). Holder, registrant and rDNS all agree, which is the pattern of an organisation numbering its own space rather than an operator carrying somebody else's traffic.
The shape tells you the role. A single upstream means no transit function: this AS exists so the publisher can hold its address space independently of any one provider, not to sell connectivity. A quarter-thousand addresses is the size of a publishing house's public-facing edge (web, mail, remote access), not of an eyeball access network. The 200.80/8 range is LACNIC space, consistent with an Argentine registrant.
Notable
Do not read anything about the network's age from the low AS number. What the evidence supports is narrow and solid: a media enterprise's own small, self-registered, self-named block, single-homed, used for the company's own services.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
