Summary

Citibank N.A.

Hong Kong · AI-generated

business corporate finance internal

The AS handle CITI-HK-ISP_PEER-AP is held by Citibank N.A.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname CITICORP-C and a reverse DNS record pointing to unitedarabemiratescob.citibank.ae.
  • The AS announces 1536 IPv4 addresses across 6 prefixes with only 3 observed neighbours, a ratio indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • All registrants for the announced prefixes are listed as Citibank N.A., fully consistent with the AS holder.
  • The address inventory consists of six /24 blocks within the 192.193.0.0/16 range, all located in Hong Kong, reflecting a finely subdivided corporate estate.

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 1,783 prefixes, as published 2026-10-17. 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.
