Summary

Shanghai Ruisu Network Technology

China · AI-generated

hosting idc china

RUISU-51IDC is operated by Shanghai Ruisu Network Technology Co.,Ltd.

What it's used for

  • The address space carries IDC infrastructure, as indicated by the netname Ruisu-51IDC and the registrant IRT-51IDC-CN across all announced prefixes.
  • The AS announces 1024 IPv4 addresses across 4 prefixes with 1 observed neighbour, a ratio consistent with a hosting or data center provider rather than a transit carrier.
  • Traffic from this AS consists of hosted services and data center workloads, given the operator's business as a network technology and IDC provider.

Notable

  • All four announced prefixes share the netname Ruisu-51IDC and registrant IRT-51IDC-CN, which aligns with the AS holder.
  • The address inventory consists of four /24 blocks, all located in China, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
