Summary

NORC at the University of Chicago

United States of America · AI-generated

business research university internal

The AS handle NORC-1 is held by NORC at the University of Chicago.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by registrants National Oppinion and National Opinion Research Center associated with netnames UU-65-213-192 and D393-OAK01-192-184-121-0-24.
  • With 768 IPv4 addresses and 2 IPv6 prefixes announced against only 3 observed neighbours, the ratio indicates a small, self-contained internal network rather than a transit or access provider.

Notable

  • Registrants largely align with the announcer, showing National Oppinion and National Opinion Research Center, though one prefix is registered to Latisys-Ashburn, LLC under netname PTPTECH-ARIN-BLK4.
  • The address inventory consists of three distinct IPv4 /24 blocks and two IPv6 /48 prefixes, reflecting a finely subdivided internal estate for a research organization.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
