About this network

SANDY is one of MTS PJSC's regional fixed-line networks, serving Nizhny Novgorod. The handle preserves Sandy, the local ISP the network grew out of, which passed through Komstar-Regiony before MTS absorbed Komstar in 2011.

What it's used for

• Regional fixed broadband and associated services in the Nizhny Novgorod area: roughly 45k IPv4 addresses across ~20 prefixes, mostly in 5.227.0.0/16 plus older 194.190.x and 62.220.x blocks.
• Home-user pools plus carrier-grade NAT for dynamic subscribers; a single observed upstream, so the AS sits behind MTS's own backbone rather than buying transit.

Notable

• Reverse DNS on the older blocks confirms eyeball use: dynamic home pools named NNN-NN-NNN-NN-dyn.hn.nnov.stream.ru and NAT gateways stream-nat-01 (stream.ru is the local access brand). Most-specific inetnums read MTS-FX-NN-NET, ISP-MTS-Volga and "Mobile TeleSystems PJSC, Nizhny Novgorod region" — an MTS fixed-access assignment, not the mobile core.
• The newer 5.227.0.0/16 space returned few PTRs when sampled, but the lineage and the resolving older blocks both point to consumer broadband.

Interesting

• MTS is far better known as a mobile operator, but this AS is fixed-line. MTS's mobile network is numbered elsewhere, so an address here should not be read as a cellular one.
