AS204921 announces 1 IPv4 prefixes covering 1,024 addresses and 6 IPv6 prefixes.

About this network

The AS handle YUNMEE-NETWORK is held by YunZheng Network.

What it's used for

• The address space carries research and anycast services, as indicated by the netnames NET-YUNZHENG-RESEARCH-APAC and YunZhengLAB-Orbit-Anycast.
• The AS announces 768 IPv4 addresses across 2 prefixes and 13 IPv6 prefixes, while maintaining 43 observed neighbours. This ratio of a small address inventory against a high number of peering partners indicates a transit or research network role rather than a large access provider.
• Traffic from this AS consists of research data, academic collaboration, and anycast service endpoints, consistent with its classification as an educational and research network.

Notable

• The registrant zhenyun sun matches the AS holder and the netnames for both announced IPv4 prefixes.
• The address inventory is compact, consisting of a single /23 and a single /24 in IPv4, alongside a set of /46 to /48 prefixes in IPv6.
