business china ipv4

CNBIDCC is held by Beijing Beilong Yunhai Network Data Technology Corporation.

What it's used for

  • The address space is registered under the netname CNBIDCC with registrant IRT-CNBIDCC-CN across all announced prefixes.
  • The AS announces 3328 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale internal or business network rather than a transit provider.
  • The inventory consists of fragmented /24 and /23 blocks within the 223.0.0.0/8 range, suggesting a corporate estate with site-by-site segmentation.

Notable

  • All registrants agree with the announcer, consistently listing IRT-CNBIDCC-CN for every prefix.
  • The address inventory is composed of nine distinct IPv4 prefixes, including one /22, one /23, and seven /24s, all located in China.

Reputation

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
