AS24363 — CNGI-JNN-IX-AS-AP CERNET2 IX at Shandong University

AS24363 announces 0 IPv4 prefixes covering 0 addresses and 7 IPv6 prefixes.

About this network

CNGI-JNN-IX-AS-AP is the autonomous system for the CERNET2 Internet Exchange Point hosted at Shandong University.

What it's used for

• The address space is registered under the netname NJR-CERNET with registrants CERNET Helpdesk and IRT-CERNET-AP, indicating it carries traffic for the China Education and Research Network (CERNET).
• The AS announces 6,656 IPv4 addresses across 3 prefixes and 7 IPv6 prefixes, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio suggests a role focused on aggregating and exchanging traffic for the CERNET2 backbone rather than providing general transit.

Notable

• All three announced IPv4 prefixes share the same registrant (CERNET Helpdesk) and netname (NJR-CERNET), confirming a unified administrative domain for the exchange point's address space.
• The inventory consists of a large contiguous block in the 121.250.0.0/16 range and several distinct IPv6 /32 and /48 prefixes, reflecting the dual-stack nature of the CERNET2 infrastructure.
