Summary

North Central College

United States of America · AI-generated

education business small

The AS handle NCC-23-ASN is held by North Central College.

What it's used for

  • The address space carries institutional infrastructure, evidenced by the reverse DNS record burrus.noctrl.edu and the netname NOCTRL registered to North Central College's Information Technology Services.
  • The network announces 512 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit provider.

Notable

  • Registrants differ from the announcer for one prefix: 64.107.184.0/24 is registered to Illinois Century Network under the netname ICN1, while 192.160.165.0/24 is registered to North Central College.
  • The inventory consists of two distinct /24 blocks, one of which appears to be legacy or leased space from a different operator, while the other is directly managed by the college.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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 1,783 prefixes, as published 2026-10-20. 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.
