hosting idc china telecom

CHINATELECOM-GUANGDONG-IDC is operated by China Telecom Guangdong IDC.

What it's used for

  • The address space carries data center and infrastructure traffic, as indicated by the AS handle "IDC" and registrant netnames such as RJNET, ZSQY-CN, and QYCC.
  • The AS announces 34,048 IPv4 addresses across 4 prefixes and 31 IPv6 prefixes, while maintaining only 2 observed routing neighbours. This high address-to-neighbour ratio indicates a hosting or infrastructure role rather than transit.
  • Traffic from this AS consists of web servers, API endpoints, and data center workloads hosted within China Telecom's Guangdong facilities.

Notable

  • Registrants for the largest prefixes include IRT-CNISP-CN, IRT-ZSQY-CN-CN, and IRT-QYCC-CN, which align with the China Telecom Guangdong IDC identity.
  • The inventory is dominated by a single large /17 block (121.201.0.0/17) alongside smaller /23 and /24 blocks, suggesting a consolidated corporate estate with specific sub-allocations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
