Summary
China Telecom ChinaNet IDC (Shaanxi)
hosting legacy
Autonomous System 4835 (CHINANET-IDC-SN) is a China Telecom network dedicated to IDC (internet data centre) address space, anchored on the provincial ChinaNet network carrying the SN designator and the data centres in Xi'an.
What it's used for
- Announcing China Telecom's data-centre and hosting address space: servers, colocated customers and the Chinese IDC operators that take space and transit from ChinaNet.
- Blocks originated here include both ChinaNet's own provincial IDC ranges and address space registered to independent Chinese hosting companies.
Notable
- A hosting network, not an eyeball one. Addresses seen from this AS are far more likely to be servers than home broadband users, which matters when interpreting traffic from it.
- It is a provincial IDC AS inside the much larger China Telecom group, and should not be conflated with the group's mass-market backbone (AS4134, ChinaNet "163") or its premium CN2 core (AS4809).
Interesting
- The registry description of the province is ambiguous in the classic way: APNIC's text and the
SNcode point at Shaanxi, and the individual IDC blocks are registered in Xi'an, but the same records have long been transcribed as "Shanxi" too. The two provinces are distinct, and the paperwork does not always say which one it means.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
