Summary

Concordia College

United States of America · AI-generated

education college network

CONCORDIA-COLLEGE is the autonomous system for Concordia College.

What it's used for

  • The space carries the college's internal network, evidenced by the netname CORD and the reverse DNS record router1.cord.edu.
  • The AS announces 4096 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained campus network rather than a transit provider.

Notable

  • The RDAP registrant Concordia College matches the AS holder, confirming consistent ownership of the address space.
  • The inventory consists of a single IPv4 prefix, 138.129.240.0/20, and one IPv6 prefix, 2602:fd2a::/40, representing a compact and unified address estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
