what's this?
RPKI hygiene: B how networks compare →
90.8% of checked blocks have valid RPKI ROA coverage (89 of 98)
RPKI-inferred operator JCOM Co., Ltd.
Nearly all of this network's RPKI-covered space is cryptographically authorized for this single operator — the registered netname is likely one of its internal infrastructure labels.
No discrepancies found among checked blocks.
