business enterprise corporate
The AS handle CIO-ORGANIZATION is held by IBM.
What it's used for
- The address space carries corporate infrastructure, with netnames explicitly labeled
IBM-COMMERCIAL,IBM-RSCH-NET1, andIBMPOP-MUMBAI. - The inventory consists of 7,680 IPv4 addresses across 10 prefixes and 56 IPv6 prefixes, observed against only 2 neighbours, indicating a self-contained internal corporate estate rather than a transit or access network.
Notable
- Registrants align with the announcer, listing
IBM; Org Abusefor most blocks andIBM-1-Zfor the Mumbai POP prefixes. - The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a large multinational enterprise.

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 2026-10-13, 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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
