Summary
China Next Generation Internet CERNET2
education research ipv6 backbone
CNGI-CERNET2-AS-AP is operated by China Next Generation Internet CERNET2.
What it's used for
- The address space carries the China Education and Research Network (CERNET) backbone, serving as the experiment platform for next-generation Internet applications under the Ministry of Education.
- The AS announces 891 IPv6 prefixes and 0 IPv4 addresses, with 47 observed neighbours, indicating a high-capacity research and education backbone rather than a residential access network.
Notable
- RDAP registrant data is unavailable, so registrant alignment with the announcer cannot be verified from the pack.
- The address inventory consists entirely of IPv6 space within the 2001:250::/47 range, reflecting the network's focus on IPv6 deployment for the CNGI project.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
