About this network

ASN-MATRIXMOBILE — the network of Matrix Telecom LLC, a Moscow-based telecom operator trading as Matrix Mobile.

What it's used for

• Carrying subscriber traffic for Matrix Mobile's service, alongside the operator's own infrastructure.
• Multi-homed through several Russian upstream carriers rather than depending on a single transit provider.

Notable

• Mobile operator address space behaves differently from fixed broadband: a single IP can be shared by very many handsets behind carrier-grade NAT, so per-IP reputation and geolocation are both coarse. Treat a hit here as "a Matrix Mobile subscriber somewhere in Russia", not as a specific location.
• Registered with RIPE NCC as a Local Internet Registry, which is what lets it hold and sub-assign its own address blocks.

Interesting

• The MATRIXMOBILE handle is the clearest signal of what the ASN is for; the legal entity name (Matrix Telecom LLC) gives no hint of the mobile side.
