AS6672 ASRELCOMSPB

ASRELCOMSPB is LLC Relcom-SPB, the St Petersburg arm of the Relcom network —

one of the oldest names in Russian networking.

What it's used for

• Internet access and connectivity in the St Petersburg region. Backbone reverse DNS resolves under Relcom.net with names such as StPetersburg-R-1.
• A small network by address count: roughly 1.5k IPv4 addresses across a couple of prefixes, plus an IPv6 /32.

Notable

• Relcom ("RELiable COMmunications") began at the Kurchatov Institute in 1990 and became the first commercial internet service provider in the USSR. Relcom-SPB is a regional operator carrying that name, not the original Moscow entity.

Interesting

• Part of its address space carries generic third-party reverse-DNS names rather than Relcom's own, which suggests some of the block is sublet or used for hosting rather than for the operator's own access customers. The exact split is not clear from public data, so treat any single label for this AS with caution.
