About this network

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.
