Summary

CHINANET Guangdong province network

China · AI-generated

telecom residential business china

CT-GUANGZHOU-IDC is operated by CHINANET Guangdong province network, a division of China Telecom.

What it's used for

  • The address space carries a mix of enterprise and residential services, evidenced by netnames such as UCLOUD-NET, HWCSNET, JDCOM, BJKSCNET, and CHINANET-GD.
  • The AS announces 188,416 IPv4 addresses across 82 prefixes and 27 IPv6 prefixes, while maintaining only 10 observed neighbours, a ratio indicative of a large access or eyeball network rather than a transit provider.
  • Traffic from this AS consists primarily of subscriber eyeballs and business endpoints within Guangdong province, serving both residential broadband users and corporate clients like Huawei and JD.com.

Notable

  • Registrants vary across the inventory, including IRT-CNNIC-CN, IRT-GZPRBNET-CN, IRT-BJKSCNET-CN, IRT-JDCOM-CN, and IRT-CHINANET-CN, reflecting a diverse set of leased or allocated blocks under the CHINANET umbrella.
  • The inventory is composed of numerous /18, /19, and /20 blocks, with the largest being 42.240.128.0/18, 106.75.128.0/18, and 124.40.128.0/18, indicating a finely subdivided corporate and consumer estate.

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.
