What it's used for

• The space carries internal research and high-performance computing traffic, as indicated by the registrant netname RU-KIAM-20021028 and the institute's focus on computational mathematics.
• The AS announces a single IPv4 prefix, 217.9.80.0/22, comprising 1024 addresses, and maintains 11 observed neighbours, a ratio consistent with a dedicated institutional network rather than a transit provider.

Notable
