Summary

LoCyan Network

China · AI-generated

business enterprise china

LOCYAN-NETWORK-AS is held by Shanghai Yingyun Network Technology Co., Ltd.

What it's used for

  • The space carries the netname AMPRNET with registrant Amateur Radio Digital Communications, indicating usage for amateur radio digital communications infrastructure.
  • The AS announces 256 IPv4 addresses and 3 IPv6 prefixes against 48 observed neighbours, a ratio that suggests a transit or interconnection role rather than a large access network.
  • Traffic from this AS consists of enterprise and amateur radio data communications, given the operator's identity as a network technology company and the specific amateur radio registrant.

Notable

  • The RDAP registrant for the announced IPv4 prefix is Amateur Radio Digital Communications, which differs from the AS holder Shanghai Yingyun Network Technology Co., Ltd., suggesting the address space is leased or managed for a specific amateur radio community.
  • The address inventory consists of a single IPv4 /24 block and three IPv6 /48 prefixes, all located in China.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
