Summary

China Networks Inter-Exchange (CNIX)

China · AI-generated

transit legacy

Autonomous System 4847 (CNIX-AP) is China Networks Inter-Exchange, a Beijing-anchored Chinese interconnection and transit network. It is by far the largest network in this stretch of the AS range, originating several million IPv4 addresses across roughly a thousand prefixes.

What it's used for

  • Carrying and originating address space on behalf of a long tail of Chinese networks: provincial ChinaNet blocks, independent broadband operators and data-centre companies all appear behind this AS.
  • It takes transit from the major Chinese backbones and from international carriers, and sits upstream of a large number of smaller Chinese networks.

Notable

  • A mixed-bag origin AS. Because it announces space registered to many different Chinese organisations, an address seen from AS4847 can be a data-centre server, a second-tier ISP's customer, or backbone infrastructure. Attribution is best done from the individual prefix, not from the AS.
  • The APNIC record still carries its original description of an international link at Beijing connected to Sprint's global network, a snapshot of the era when China's outside connectivity ran through a small number of US carrier circuits.

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: 443 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.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
