Summary
China Telecom Shanghai (ChinaNet Shanghai MAN)
isp legacy
Autonomous System 4811 (CHINANET-SHANGHAI-MAN) is China Telecom's Shanghai metropolitan area network — the access network serving the Shanghai municipality.
What it's used for
- Fixed broadband and business internet access for homes and companies in Shanghai, attached to China Telecom's ChinaNet backbone.
Notable
- An eyeball network with a very large IPv4 footprint: nearly all of it lands on end-user connections in a single city region.
- Chinese carriers run province-by-province networks, so this AS is Shanghai specifically, distinct from the national ChinaNet backbone at AS4134 and from other provincial ASNs under the same China Telecom group.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
