Prices in USD per IP, excl. VAT. Buy and sell, the same for RIPE, ARIN and APNIC: $24 for /24–/22, $21 for /21–/18, $15 for /17–/15. Lease per IP per month: RIPE $0.38, ARIN $0.32, APNIC $0.40; leasing out pays the owner these rates minus our 15%. Euro amounts are converted at a fixed rate of €0.86 per $1. Sale amounts are shown after our commission. Final price depends on the block, its reputation and the terms.
