AS10849 DCCCD

DCCCD is the Dallas County Community College District, which since 2020 has operated under the single name Dallas College — a multi-campus public community college system serving Dallas County, Texas.

What it's used for

Campus networking for a large public college. RIS sees 3 announced IPv4 prefixes carrying 65,536 addresses and no IPv6, against 2 observed BGP neighbours. The announcement that does all the work is a single /16, 144.162.0.0/16; the other prefixes are more-specifics carved out of it.

That is a textbook education-network profile. A whole /16 — enough for tens of thousands of student, staff and lab machines across campuses — announced behind just two upstreams, with no peering fabric of its own. Universities and college districts were among the earliest institutions to receive class-B space and, unlike most corporations of the era, they kept it: the address count reflects a 1990s allocation policy, not present-day demand.

The 144.x range sits squarely in the block ARIN handed to US educational and research institutions, which corroborates the holder rather than merely echoing it.

Notable

Two BGP neighbours is worth reading carefully. Many US colleges reach the internet through a state or regional research network rather than buying commodity transit directly, and a low peer count with a single large origin is the shape that produces.

No reverse DNS was returned for the two addresses sampled here — far too small a sample to conclude anything, and nothing is concluded from it.
