Summary
Morningstar
enterprise legacy
Autonomous System 7761 (AS-350E) belongs to Morningstar, Inc., the Chicago-based investment-research and financial-data company.
What it's used for
- Carrying part of Morningstar's own corporate and market-data infrastructure. It announces a single
/24,206.220.16.0/24, registered under the netnameLIM-NET. LIMis Logical Information Machines, a Chicago commodities and energy data-analytics firm that Morningstar acquired in 2009; the block and the ASN now sit under the Morningstar organisation. The network is used for data delivery and internal systems rather than for anything sold as connectivity.
Notable
- This is an enterprise AS with a deliberately minimal footprint: 256 IPv4 addresses, one prefix. As with many financial-data firms, the point of holding an ASN is provider independence and multihoming, not address volume.
- The
AS-350Ehandle is opaque and tells you nothing about the holder — one more reminder that ASN handles are free-form strings chosen by whoever registered them, and are not a reliable identifier.
Interesting
- Market-data and research firms cluster their networks around Chicago's financial infrastructure, and Morningstar's absorbed LIM network is a small piece of that ecosystem — the visible remnant, in the routing table, of a company that no longer exists as an independent brand.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
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.

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 1,778 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.
