AS38587 CERNET-IDC-AP - CERNET Internet Data Center
Unclassified ARIN
Summary
CERNET Internet Data Center
education datacenter ipv6
CERNET-IDC-AP is operated by CERNET Internet Data Center.
What it's used for
- The address space carries IPv6 infrastructure for the China Education and Research Network (CERNET), specifically its data center operations.
- The AS announces 8 IPv6 prefixes and 0 IPv4 addresses, with a single observed neighbour, indicating a specialized internal or peering role rather than general transit.
- Traffic from this AS consists of data center services and research network infrastructure supporting Chinese academic institutions.
Notable
- The registrant CERNET Internet Data Center aligns with the AS handle and the educational sector focus.
- The inventory is exclusively IPv6, with no IPv4 prefixes in the announced set or inventory.
- The AS has been observed in routing tables since 2008.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, 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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
