Summary
China Telecom CN2 (Next Generation Carrier Network)
transit legacy
Autonomous System 4809 (CHINATELECOM-CORE-WAN-CN2) is the core of CN2, China Telecom's "Next Generation Carrier Network" — a premium backbone kept separate from the mass-market ChinaNet network.
What it's used for
- Carrier backbone and transit, particularly for international routes in and out of China and for premium enterprise and wholesale services.
Notable
- Backbone infrastructure, not an access network: the addresses here are router interfaces and core links rather than customer endpoints.
- CN2 is widely regarded as China Telecom's higher-quality path for cross-border traffic, and is routinely distinguished from ChinaNet — see AS4134 for the mass-market "163" backbone.
Interesting
- CN2 routes are a perennial topic among operators serving Chinese users, because which of China Telecom's two backbones a route lands on can make a large difference to latency and loss on international paths.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
