Summary
Citigroup Inc.
enterprise legacy
CITI7 is one of a set of autonomous systems operated by Citigroup, the global
banking and financial services company.
What it's used for
- Citigroup's own corporate and banking network: internal systems, branch and office connectivity, and the bank's internet-facing services.
- The announced space includes Latin American ranges alongside the bank's legacy US blocks, reflecting Citi's international footprint.
Notable
- This is enterprise address space, not consumer or hosting space. IPs here belong to a bank's own infrastructure, so they are a poor fit for assumptions about end-user or server-tenant traffic.
- ARIN's registration dates to 1993. Large banks were early adopters of their own routed address space, and Citi's numbering scheme runs across several sibling ASNs including [AS3081](https://asn.ipinfo.app/AS3081).
