Summary

Citigroup

United States of America · AI-generated

business finance corporate

The AS handle CITIGROUP-BANAMEX is held by Citigroup Inc.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames CITICORP-C and the registrant Citibank N.A. for the 192.193.204.0/23 and 192.193.206.0/24 blocks.
  • The 200.52.97.0/24 and 200.52.98.0/24 blocks are registered to Banco Nacional de Mexico, S.A. Integrante del Grupo Financiero Banamex, reflecting the historical integration of Banamex into Citigroup.
  • With 1280 IPv4 addresses announced across 4 prefixes and only 2 observed neighbours, the inventory represents a finely subdivided internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer's identity, showing Citibank N.A. for the US-based blocks and Banco Nacional de Mexico, S.A. for the legacy Mexican blocks.
  • Citigroup was formed in 1998 by the merger of Citicorp and Travelers Group, Inc., and subsequently acquired Banamex, which explains the mixed registrant history in the address inventory.
  • The inventory consists of four distinct IPv4 prefixes with no IPv6 announcements, indicating a legacy IPv4-only corporate footprint.

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 1,781 prefixes, as published 2026-10-16. 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.
