Registered organisation
Leibniz-Rechenzentrum
Address space registered to Leibniz-Rechenzentrum, and where it is announced from.
Registered holders come from the bulk whois that RIPE, APNIC and AFRINIC publish. ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
