telecom residential china hunan

CT-HUNAN-CHANGSHA-IDC is operated by China Telecom Hunan.

What it's used for

  • The address space carries CHINANET-HN netnames, registered to CHINANET HUNAN, indicating consumer broadband and data center services in Hunan province.
  • The AS announces 152,832 IPv4 addresses across 99 prefixes and 32 IPv6 prefixes, with only 2 observed neighbours, a ratio characteristic of an access network serving end-user traffic.
  • Traffic from this AS consists of subscriber eyeballs and data center workloads for China Telecom's Hunan regional operations.

Notable

  • Registrants for all sampled prefixes are CHINANET HUNAN under IRT-CHINANET-CN, consistent with the announcer's identity as a China Telecom regional entity.
  • The inventory includes large blocks such as 175.6.64.0/18 and 118.252.224.0/19, alongside finer subdivisions, reflecting a mixed portfolio of legacy and modern allocations.

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.
