About this network

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.
