CHINATELECOM-HLJ-AS-AP is the autonomous system for China Telecom Heilongjiang, the provincial network of China Telecom in Heilongjiang province.

What it's used for

  • The address space is registered under the netname CHINANET-HL with registrant IRT-CHINANET-CN, indicating it carries China Telecom's consumer and business access traffic in the Heilongjiang region.
  • The AS announces 151,296 IPv4 addresses across 29 prefixes and 9 IPv6 prefixes, while maintaining only 1 observed neighbour. This high address-to-neighbour ratio is characteristic of a large access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of the largest prefixes, including 112.101.0.0/16 and 112.100.128.0/17, are listed as IRT-CHINANET-CN, which aligns with the announcer's identity as a China Telecom provincial network.
  • The address inventory is dominated by blocks in the 112.100.0.0/16 and 112.101.0.0/16 ranges, with additional space in 123.167.0.0/16 and 219.147.0.0/16, reflecting a typical regional ISP allocation.

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

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 1,775 prefixes, as published 2026-10-11. 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.
