education research transit china

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.
  • The inventory includes a single IPv4 prefix (118.229.40.0/21) and three IPv6 prefixes, including a large /32 block.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
