Summary

China Telecom Shanghai (ChinaNet Shanghai MAN)

China · AI-generated

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: 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.
