telecom residential china access

The AS handle CHINANET-SCIDC-AS-AP is held by China Telecom Sichuan.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames CHINANET-SC and WEST263 associated with registrants IRT-CHINANET-CN and IRT-WEST263.
  • The AS announces 241,664 IPv4 addresses across 260 prefixes and 69 IPv6 prefixes, while maintaining only 9 observed neighbours, a ratio characteristic of an access network serving end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business connections within the Sichuan province of China.

Notable

  • Registrants IRT-CHINANET-CN and IRT-WEST263 align with the announcer's identity as a regional China Telecom entity.
  • The inventory is finely subdivided into numerous /20 and /21 blocks, reflecting site-by-site segmentation typical of a large regional carrier.

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: 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.
