AS3073 — CITI7

AS3073 announces 4 IPv4 prefixes covering 1,280 addresses and 0 IPv6 prefixes.

About this network

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.
