About this network

AS11237 belongs to Universidad EAFIT, the private university in Medellín, Colombia (Escuela de Administración, Finanzas e Instituto Tecnológico). It is a single-institution campus network in LACNIC space.

What it's used for

Campus connectivity for one university. RIS observes a single IPv4 prefix, 200.12.176.0/20 (4,096 addresses), a single IPv6 /48 (2800:b70:49::/48), and three observed neighbours. That is about as clean an academic-edge profile as exists: one aggregate of legacy LACNIC 200.x space, one IPv6 assignment, and a small number of upstreams — typically a commercial transit provider plus the national research-and-education network.

The 200.12.176.0/20 block is registered as an inetnum covering exactly the announced range, so the university announces only its own registered space. There is no third-party registrant, no scattered /24s from multiple RIRs, and nothing resembling the IP-leasing shape.

Notable

A /20 for a university of EAFIT's size is a modest allocation by North American standards and reflects LACNIC's tighter address policy: Latin American campuses generally run NAT for the student and staff population and reserve public addresses for servers and infrastructure. The presence of a single routed IPv6 /48 (rather than a /32 or /44) points the same way — an end-site assignment, not a provider aggregate.

Interesting

EAFIT has long been active in Colombian research networking; a low AS number with a clean, minimal announcement is typical of institutions that got connected early and never needed to grow the footprint.
