About this network
CHINA169-GZ is the autonomous system for China Unicom in Guangdong province.
What it's used for
- The address space carries residential and mobile traffic for the Guangdong region, evidenced by netnames such as UNICOM-GD and UNICOM-GDDG.
- With 2,657,024 IPv4 addresses announced across 487 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates a large access network rather than a transit provider.
Notable
- Registrants are consistent with the announcer, primarily IRT-CU-CN for the UNICOM-GD netnames, with one prefix registered to CNCGROUP GD.
- The inventory includes a mix of /15, /16, and /17 blocks, including large allocations like 27.42.0.0/15 and 58.252.0.0/15, alongside 3,441 IPv6 prefixes.
