Summary

China · AI-generated

business china ipv4

CNISP-UNION is operated by CNISP-Union Technology (Beijing) Co., Ltd.

What it's used for

  • The address space carries business or enterprise traffic, indicated by netnames TopnewNET and TopnewInfoNET across the inventory.
  • The AS announces 3328 IPv4 addresses across 6 prefixes while maintaining only 1 observed neighbour, a ratio that suggests a local access or internal corporate network rather than a transit provider.

Notable

  • Registrants for the five largest prefixes are consistently IRT-CNISP-CN with netname TopnewNET, aligning with the registry holder, while the smallest prefix 103.249.244.0/24 shows netname TopnewInfoNET with an unknown registrant.
  • The address inventory consists of six distinct IPv4 blocks, all located in China, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
