Summary
DYXnet (Diyixian.com Limited)
hosting isp transit legacy
AS9584 (GENESIS-AP) is held by Diyixian.com Limited, trading as DYXnet, a Hong Kong network and cloud-services operator established in 1999 and now a wholly-owned subsidiary of VNET Group (formerly 21Vianet), the Chinese carrier-neutral data-centre company. DYXnet sells MPLS and SD-WAN enterprise networking, cloud connectivity, security services and colocation across Hong Kong and Greater China.
What it's used for
The evidence describes a mid-sized commercial provider, not an eyeball ISP and not a pure hosting farm. RIS observes 32 IPv4 prefixes carrying 66,048 addresses, 5 IPv6 prefixes under 2001:eb0::/32, and 45 BGP neighbours. That neighbour count is the interesting number: 45 peers is far more than any enterprise needs and far fewer than a wholesale transit carrier maintains. It is the profile of a regional provider that peers actively to serve its own customers well, particularly across Hong Kong's exchange fabric. Reverse DNS backs this up: virtually every sampled address resolves to a static-ip-….rev.dyxnet.com record. Those are provider-assigned static allocations, which is what a business connectivity and colocation customer gets, not the dynamic pool naming an eyeball network would use. A stray PTR such as ns1.mfasia.com in 202.66.144.0 is a customer's own hostname sitting inside DYXnet space, and shows what the address range carries rather than who holds it.
Notable
- The address space is drawn from several APNIC-era ranges (
202.134.64.0/18,152.104.0.0/17,202.65.192.0/19,202.66.128.0/19,219.90.112.0/20,114.142.144.0/20), the accumulation you would expect from a provider operating since the late 1990s. - DYXnet's positioning is corporate: MPLS VPN sites and hosted client facilities across Hong Kong, mainland China, Taiwan, Singapore and Vietnam. Addresses in this AS are much more likely to be a business site or a hosted service than a home user.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
