China Unicom ASN, MCC/MNC and IP prefixes

China Unicom is a network operator in China under China United Network Communications Group Company Limited. The registry records five ASNs, of which AS4837, the China169 backbone, holds the mobile role; the rest are enterprise or undocumented. Its recorded mobile country and network codes are 460-01 and 460-09, and it runs 4G LTE and 5G.

Five ASNs are recorded for China Unicom. AS4837, the China169 backbone, is the one with a documented mobile role, and at the last probe it announced 1,510 IPv4 prefixes against 652 IPv6 prefixes, with a PeeringDB record naming it China Unicom and typing it NSP. AS9929, the Industrial Internet backbone, is recorded as enterprise with 228 IPv4 and 146 IPv6 prefixes and a PeeringDB entry under China Unicom Industrial Internet Backbone. AS4808 is the Beijing provincial network with no documented role, AS10206 is a cloud network, and AS9800 was not announcing routes at the last probe.

An address whose origin ASN is one of these is routed by China Unicom. Only AS4837 has a mobile role in the registry, and that backbone also carries fixed broadband subscriber traffic, so origin in AS4837 does not on its own mean a handset. AS4808 has no documented role, so an address there could be mobile, fixed or enterprise, and the ASN alone does not settle it. AS9929 and AS10206 are enterprise and cloud networks, which points away from consumer mobile traffic.

Research note. AS4837 (China169 backbone) is China Unicom's unified consumer backbone carrying both fixed broadband and mobile subscriber traffic; PeeringDB record: name 'China Unicom', aka AS-CNCGROUP, website chinaunicom.cn, type NSP. AS9929 (CUII) is the premium Industrial Internet backbone (PeeringDB name 'China Unicom Industrial Internet Backbone'), enterprise-grade, not the consumer mobile network. AS4808 is the Beijing provincial network (role not determined from fetched sources). AS9800 holder is 'UNICOM - CHINA UNICOM' but RIPEstat reports it as not announced. AS10206 is China Unicom Zhongwei Cloud (enterprise/cloud). Legacy CNCGROUP candidates AS4659, AS4799 and AS4814 (China Netcom, merged into China Unicom on 15 Oct 2008 per chinaunicom.com.hk profile) are all unannounced per RIPEstat and were omitted. PeeringDB was rate-limited (HTTP 429) for AS4808/AS9800/AS10206, so those rest on RIPEstat only. MCC/MNC: Wikipedia lists 460-01 operational (LTE/5G) and 460-09 operational; 460-06 (GSM/UMTS) was shut down Dec 2023 and dropped.
