Summary

Oriental Cable Network (Shanghai)

China · AI-generated

legacy isp residential

AS9812 (CNNIC-CN-COLNET) is held by Oriental Cable Network Co., Ltd (东方有线), the cable operator for Shanghai. OCN runs the city's cable-television metropolitan network and sells broadband over it under the Cable Plus brand; this AS is the eyeball network behind that service.

What it's used for

RIS sees 137 IPv4 prefixes carrying 1,785,856 addresses, 8 IPv6 prefixes, and only 4 BGP neighbours. That ratio is the definition of an access network: nearly 1.8 million addresses is a serious residential footprint, but four neighbours means it sells nothing wholesale and simply buys transit to get its own subscribers to the internet. The inventory backs it up — three /16s and a long tail of /17s and /18s (219.233, 223.248–223.251, 218.242, 124.151, 111.214, 60.63, 58.25 and more), the contiguous, heavily-aggregated space of a single metro operator rather than a scatter of acquired blocks. Sampled reverse DNS lands consistently on reserve.cableplus.com.cn across several unrelated prefixes, tying the space directly to OCN's own broadband brand.

Notable

  • The CNNIC-CN-COLNET handle is a CNNIC-era label and does not name the operator — the identity comes from the Cable Plus rDNS and the registry holder, not the handle.
  • IPv6 is deployed: eight prefixes including 2400:6600::/32 and 2401:800::/33, unusual for a Chinese cable operator of this generation.
  • This is cable-plant broadband, distinct from Shanghai Telecom or Unicom's telco networks in the same city.

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 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
