AS24361 announces 1 IPv4 prefixes covering 65,536 addresses and 37 IPv6 prefixes.

About this network

CNGI-NJ-IX-AS-AP is operated by CERNET Helpdesk.

What it's used for

• The address space carries CERNET (China Education and Research Network) infrastructure, with netnames NJR-CERNET and CERNET-CN registered to CERNET Helpdesk.
• The AS announces 161,536 IPv4 addresses and 45 IPv6 prefixes, with only 3 observed neighbours, indicating a role as an Internet Exchange Point or internal education network rather than a transit provider.

Notable

• All registrants for the largest prefixes are CERNET Helpdesk, consistent with the announcer's identity as a CERNET facility.
• The inventory consists of 19 IPv4 prefixes, including a large /16 block (223.3.0.0/16) and multiple /17 to /24 blocks, reflecting a segmented education network estate.
