AS23910 — CNGI-CERNET2-AS-AP - China Next Generation Internet CERNET2

AS23910 announces 0 IPv4 prefixes covering 0 addresses and 13 IPv6 prefixes.

About this network

CNGI-CERNET2-AS-AP is operated by China Next Generation Internet CERNET2.

What it's used for

• The address space carries the China Education and Research Network (CERNET) backbone, serving as the experiment platform for next-generation Internet applications under the Ministry of Education.
• The AS announces 891 IPv6 prefixes and 0 IPv4 addresses, with 47 observed neighbours, indicating a high-capacity research and education backbone rather than a residential access network.

Notable

• RDAP registrant data is unavailable, so registrant alignment with the announcer cannot be verified from the pack.
• The address inventory consists entirely of IPv6 space within the 2001:250::/47 range, reflecting the network's focus on IPv6 deployment for the CNGI project.
