what's this?

Same name family

Separately-registered clusters whose names share “OPEN NET” — 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.

Open-Net-World 1 blocks

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.

RPKI hygiene: B how networks compare →

81.8% of checked blocks have valid RPKI ROA coverage (9 of 11)

Possible discrepancies (2)

These blocks are registered to OPEN-NET but cryptographically authorized for a different, unrelated network (2 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
