About this network
An actively routed ASN of NYSERNet (NYSERNET3-AS), the New York State Education and Research Network — a member-owned non-profit that provides high-capacity networking to universities, colleges, and research institutions across New York.
What it's used for
- Regional research-and-education backbone connectivity: linking member campuses to one another, to national research networks such as Internet2, and to commercial transit.
- Announces several thousand legacy IPv4 addresses used by NYSERNet and its member institutions.
Notable
- Institutional, not commercial: the addresses behind this ASN belong to campuses, libraries, medical centres, and research facilities rather than to residential subscribers.
- NYSERNet operates neutral colocation and interconnection facilities in New York City, which makes it a peering point as well as a network.
Interesting
- NYSERNet holds a block of consecutive low AS numbers — AS3754 and AS3756 share the same handle — a legacy of its role as one of the NSFNET-era regional networks from the mid-1980s.
