Summary

Net-Glyph Data Center

China · AI-generated

datacenter hosting china

NGDC-AS-AP is the AS handle for Net-Glyph Data Center.

What it's used for

  • The address space is registered to China Education and Research Network (CERNET) with the netname CERNET, indicating the infrastructure supports academic or research network services.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, suggesting a small-scale access or peering role rather than transit.

Notable

  • The registrant China Education and Research Network (CERNET) differs from the AS holder Net-Glyph Data Center, which may indicate leased space or a specific partnership for data center operations.
  • The inventory consists of a single IPv4 prefix 202.38.135.0/24 and one IPv6 prefix 2001:7fa:5::/48.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
