About this network

APERTURE-AS-AP is operated by AperNet (Aperture Science Limited).

What it's used for

• The address space carries VPN and network infrastructure, evidenced by netnames APERTURE-HK, APERNET-AU, and APERNET-CGNT-NET-1, and a reverse DNS entry li-dev.cn.
• The AS announces 2048 IPv4 addresses across 4 prefixes and 79 IPv6 prefixes, while maintaining 245 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role rather than an access network.
• Traffic from this AS consists of encrypted VPN tunnels and inter-AS routing traffic, consistent with AperNet's business as a global network service provider.

Notable

• Registrants vary across prefixes: Black Mesa Corporation for 23.247.138.0/23, Aperture Science Limited and AperNet Administrators for 103.152.34.0/23, AperNet for 103.181.44.0/23, and Aperture Science LLC for 209.146.104.0/23.
• The address inventory is finely subdivided into small /23 blocks and numerous /48 to /41 IPv6 prefixes, reflecting a segmented corporate or service-provider estate.
