Summary

China Financial Certification Authority

China · AI-generated

business certification finance china

CFCA-NET is operated by China Financial Certification Authority.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the consistent netname CFCA-NET across all announced prefixes.
  • The AS announces 1792 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 3 observed routing neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal services for a certification authority, including electronic certificate issuance, digital signature validation, and related financial compliance endpoints.

Notable

  • All registrants align with the announcer, identified as IRT-CFCA-NET-CN for the prefixes 210.74.40.0/22, 210.74.44.0/23, and 210.74.47.0/24.
  • The address inventory is finely subdivided into three contiguous IPv4 blocks within the 210.74.40.0/22 range, reflecting site-by-site segmentation typical of a single corporate entity.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,784 prefixes, as published 2026-10-19. 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.
