About this network
CNGI-GZ-IX-AS-AP is operated by CERNET (China Education and Research Network).
What it's used for
- The address space carries educational and research traffic, evidenced by netnames CERNET-CN and BJR-CERNET and reverse DNS entries pointing to tsinghua.edu.cn.
- The AS announces 65,792 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio indicative of an access or exchange point network rather than a transit provider.
Notable
- Registrants for all listed prefixes are consistent with the announcer, citing CERNET Helpdesk and China Education and Research Network (CERNET).
- The inventory consists primarily of the 219.223.0.0/17 block and its subdivisions, alongside smaller allocations in 202.112.0.0/16.
