About this network
The AS handle CNGI-SH-IX-AS-AP is held by CERNET2 IX at Shanghai Jiaotong University.
What it's used for
- The address space carries CERNET (China Education and Research Network) infrastructure, evidenced by netnames SHR-CERNET and CERNET-CN across all listed prefixes.
- The AS announces 317184 IPv4 addresses across 32 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio indicates a large-scale access or aggregation network rather than a transit provider.
Notable
- All registrants in the RDAP data are consistent with the announcer, listing CERNET Helpdesk and IRT-CERNET-AP for every prefix.
- The inventory consists of a mix of /16, /17, /18, and smaller blocks, primarily within the 59.77.0.0/16, 219.220.128.0/17, and 202.120.0.0/18 ranges.
