AS24353 — CNGI-XA-IX-AS-AP CERNET2 IX at Xian Jiaotong University

AS24353 announces 1 IPv4 prefixes covering 65,536 addresses and 30 IPv6 prefixes.

About this network

CNGI-XA-IX-AS-AP is operated by CERNET2 IX at Xi'an Jiaotong University.

What it's used for

• The address space carries academic and research traffic associated with the China Education and Research Network (CERNET), as indicated by the netname XAR-CERNET and registrant CERNET Helpdesk.
• The AS announces 65,536 IPv4 addresses within a single /16 prefix and 37 IPv6 prefixes, while maintaining only 2 observed routing neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

• The registrant CERNET Helpdesk aligns with the announcer's identity as a CERNET infrastructure component.
• The address inventory consists of one large IPv4 block and a fragmented set of IPv6 prefixes, all located in China.
