● verified · data.other · 0.005 USDC/call · base, solana

Calculates IPv4/IPv6 subnet details from CIDR notation — network/broadcast, netmask, wildcard (Cisco ACL) mask, binary/hex masks, usable host range, RFC classification (private/loopback/multicast), supernet, and subnet-split counts. Pass comma-separated CIDRs to detect overlaps and classify each pair (subnet/supernet/partial overlap/disjoint); multi-CIDR responses return {subnets, overlaps}.

Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).

Peak day 2026-08-29: 311 payments. Last indexed day 2026-09-05: 27. Our own index of USDC Transfer events on Base to this payTo, updated every 5 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 26 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
