China · AI-generated

ix education china ipv6

The AS handle CNGI-WH-IX-AS-AP is held by CERNET2 IX at Huazhong University of Science and Technology.

What it's used for

  • The space carries IPv6 prefixes under the 2001:250:4000::/46 range, associated with the CERNET2 Internet Exchange Point hosted at Huazhong University of Science and Technology.
  • The AS announces 50 IPv6 prefixes and 0 IPv4 addresses, with 2 observed neighbours, indicating a role focused on peering and exchange rather than transit or large-scale access.

Notable

  • The registrant name explicitly identifies the entity as an Internet Exchange Point (IX) at a major Chinese university, aligning with the educational and research infrastructure context of CERNET2.
  • The address inventory consists entirely of IPv6 space, with no IPv4 prefixes announced, reflecting the modernization of Chinese academic networks toward IPv6.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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 1,775 prefixes, as published 2026-10-11. 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.
