Possibly related to this organisation

what's this?
Same name family
Separately-registered clusters whose names share “Saint Petersburg” — often per-country or per-system registrations of the same brand, occasionally a different organisation sharing the name. Not counted in this organisation's own footprint.
Sub-allocations under carriers
IP blocks an ISP reassigned to a similarly-named customer — decoded from the ISP's own naming convention, not a direct registration.

These blocks are registered to Saint Petersburg State University but cryptographically authorized for a different, unrelated network (1 distinct holder) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
