What it's used for

• The address space carries academic infrastructure, evidenced by the reverse DNS record MPEI-66.mpei.ac.ru pointing to the university's domain.
• The AS announces a single IPv4 prefix, 193.233.64.0/21, comprising 2048 addresses, with one observed neighbour, indicating a small, self-contained academic network rather than a transit or large-scale access provider.

Notable
