Summary
Dallas College (Dallas County Community College District)
education legacy
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.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
