Summary

China · AI-generated

business china apnic

CBCNET is the AS handle for Beijing Tian Wei Xin Tong technology corp. limited.

What it's used for

  • The address space carries the netname CBCnet across the majority of announced prefixes, including 43.254.228.0/22 and 103.229.216.0/22.
  • The AS announces 14,848 IPv4 addresses across 22 prefixes and 1 IPv6 prefix, while maintaining only 3 observed routing neighbours.
  • This high address-to-neighbour ratio indicates an access or internal corporate network rather than a transit provider.

Notable

  • Registrants for most prefixes are listed as unknown with the netname CBCnet, while the largest prefix 43.254.232.0/21 is registered to APNIC Hostmaster with the netname APNIC-AP-ERX.
  • The address inventory consists of 22 IPv4 prefixes and 1 IPv6 prefix, all located in China.

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 1,773 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.
