Summary

Duquesne University

United States · AI-generated

education university legacy

DQNAS is the Autonomous System of Duquesne University, a private Catholic university in Pittsburgh, Pennsylvania.

What it's used for

  • Campus networking: teaching, administration, libraries, residences and the university's own hosted services.
  • The rDNS is plainly institutional. Hosts inside the legacy 165.190.0.0/16 resolve on cr.duq.edu (directory and service machines such as ldap-warthog.cr.duq.edu), and the smaller 192.135.79.0/24 carries the campus remote-access gateway at gp.duq.edu.

Notable

  • This is an institutional network, not access or hosting. Addresses here are university-managed hosts and campus clients.
  • Its inventory is one legacy /16 plus three /24s — about 66k addresses — and it announces via very few BGP neighbours, the usual shape for a campus that takes transit from a regional research network rather than peering broadly.

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 1,779 prefixes, as published 2026-10-22. 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.
