what's this?
RPKI hygiene: B
how networks compare →
80.6%
of checked blocks have valid RPKI ROA coverage
(25 of 31)
RPKI-inferred operator
Internet Initiative Japan Inc.
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.
Possible discrepancies (1)
These blocks are registered to IIJ 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.
