China · AI-generated

payment finance infrastructure china

CPCN is the autonomous system for China Payment & Clearing Network Co., Ltd.

What it's used for

  • The address space carries the netname CPCN and registrant IRT-CPCN-CN, identifying it as the infrastructure for China's national payment and clearing systems.
  • The AS announces a single IPv4 prefix, 103.77.132.0/22, comprising 1024 addresses, with 2 observed routing neighbours.
  • Traffic from this AS consists of internal financial data exchange, settlement processing, and inter-bank communication for the People's Bank of China's clearing center.

Notable

  • The RDAP registrant IRT-CPCN-CN and netname CPCN align directly with the AS holder, China Payment & Clearing Network Co., Ltd.
  • The address inventory is a single contiguous /22 block, indicating a dedicated, isolated network segment for financial operations rather than a distributed access network.

Reputation

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 1,779 prefixes, as published 2026-10-22. 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.
