UDBQ-1 is the autonomous system for the University of Dubuque.

What it's used for

  • The space carries the university's internal network infrastructure, identified by the netname UDBQ-V4-1 and registrant University of Dubuque.
  • The AS announces 256 IPv4 addresses and 8 IPv6 prefixes against 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit provider.

Notable

  • The RDAP registrant University of Dubuque matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single IPv4 prefix, 23.135.164.0/24, and a set of contiguous IPv6 prefixes ranging from /41 to /47 within the 2602:f6ca::/47 block.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
