AS24369 — CNGI-SY-IX-AS-AP CERNET2 IX at Northeast University

AS24369 announces 7 IPv4 prefixes covering 15,360 addresses and 31 IPv6 prefixes.

About this network

CNGI-SY-IX-AS-AP is the Autonomous System for the CERNET2 Internet Exchange Point hosted at Northeast University.

What it's used for

• The address space carries CERNET infrastructure, with all eight IPv4 prefixes registered under the netname CERNET-CN and registrant IRT-CERNET-AP.
• The AS announces 17,408 IPv4 addresses across 8 prefixes and 35 IPv6 prefixes, while maintaining only 3 observed routing neighbours, a ratio consistent with an exchange point or internal academic network rather than a transit provider.

Notable

• Registrants align with the announcer, as all sampled prefixes list IRT-CERNET-AP or CERNET Helpdesk as the responsible party.
• The inventory consists of blocks within the 210.30.0.0/16 and 202.118.0.0/16 ranges, reflecting the standard allocation for China's academic and research network.
