AS11571 — LA NACION
AS11571 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.
About this network
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.
