About this network

FITI-AS-AP is operated by CERNET (China Education and Research Network).

What it's used for

• The address space carries educational and research traffic, as indicated by the netname BJR-CERNET and registrant CERNET Helpdesk.
• With 2048 IPv4 addresses and 3 IPv6 prefixes announced against 4102 observed neighbours, the high neighbour-to-address ratio indicates a transit role for the national education backbone.
• Traffic consists of data for universities, research institutions, and academic networks across China, managed under the Ministry of Education.

Notable

• Registrants align with the announcer, listing CERNET Helpdesk and IRT-CERNET-AP for the primary prefix.
• CERNET was established in 1994 as the first nationwide education and research computer network in China.
