AS11128 BERRY-2-ASN

BERRY-2-ASN belongs to Berry College, the private liberal-arts college at Mount Berry, Georgia. It is a campus network — one institution announcing its own address space.

What it's used for

Higher-education campus connectivity: students, faculty, administration and the college's public-facing services. RIS observes 3 IPv4 prefixes totalling 768 addresses — 209.209.46.0/24, 208.71.235.0/24 and 38.110.0.0/24 — and no IPv6.

Two observed BGP neighbours is the ordinary shape for a dual-homed campus: two upstream providers for redundancy, no peering fabric, no downstream customers. A carrier holding this much space would show orders of magnitude more neighbours.

Notable

Three /24s is a small footprint for a college, and it reflects an important reality about modern campus networking rather than a small campus. Nearly all student and staff devices sit behind NAT on RFC 1918 space; the publicly-routed addresses are needed only for the services that must be reachable from outside — web, mail, VPN concentrators, remote access. Institutions that were allocated large classful blocks in the 1980s still announce them; ones that arrived later, like Berry, work comfortably inside a few hundred addresses.

The registrant column splits three ways and is worth reading carefully. 209.209.46.0/24 is registered to BERRYCOLLEGE and 208.71.235.0/24 to BERRY-COLLEGE1-PFN — both the college's own ARIN objects. The third, 38.110.0.0/24, sits under COGENT-A: it is provider-assigned space out of Cogent Communications' 38.0.0.0/8, handed to a customer who announces it from their own ASN. A block registered to somebody else is the surface pattern of IP leasing, but a single /24 from a named tier-1 transit provider to a named college is simply how a multihomed customer gets addresses from its upstream.
