Autonomous system
AS21569 DBU-AS - Dallas Baptist University
Unclassified ARIN
Summary
Dallas Baptist University
education business leased
DBU-AS is the autonomous system for Dallas Baptist University.
What it's used for
- The address space carries business-grade connectivity, evidenced by reverse DNS records pointing to
biz.spectrum.comand registrant netnamesATTandCC04. - The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small institutional network relying on upstream transit providers.
Notable
- The registrants for the announced prefixes are AT&T Enterprises, LLC and Charter Communications LLC, which differ from the AS holder, indicating the university operates on leased or provisioned address space from these carriers.
- The inventory consists of two /24 blocks, one from AT&T and one from Charter, reflecting a multi-carrier setup for the university's campus infrastructure.

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 2026-11-01, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
