AS10349 TULANE

TULANE is the network of Tulane University, the private research university

in New Orleans, Louisiana. The AS carries the university's campus, hospital and

research connectivity.

What it's used for

• Campus networking: academic and administrative systems, student residential networks, library and research computing, and the university's medical-school and health-sciences campuses.
• The core of the announcement is the university's own 129.81.0.0/16 — a class-B block of the kind handed to universities in the pre-CIDR era, when higher education was most of what was on the internet.

Notable

• Education, and the routing shape confirms it. RIS sees 131,072 IPv4 addresses announced across roughly 15 prefixes, against just 3 observed BGP neighbours. Three neighbours is an end-site with a couple of commodity upstreams plus, almost certainly, a regional research-and-education network; a network selling transit at this address volume would peer with hundreds.
• Most of the deaggregation is /21–/24 slices carved out of the same /16, which is what multihomed traffic engineering across a small number of links looks like — not a customer cone.

Interesting

• One prefix, 76.165.13.0/24, sits outside the historic 129.81 block: space originated from a commercial-style allocation alongside the legacy class-B, a common pattern where a university has picked up additional addresses for a specific site or service long after its original grant.
