How this service works
IP / CIDR calculator: IPv4/IPv6 subnet math: network, range, size, netmask/wildcard, private/reserved type, contains-check and subnet split. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
Output
A JSON object containing subnet details including network address, broadcast address, IP range start/end, total and usable host count, netmask, wildcard mask, address type (private/public/reserved), result of a contains-check if requested, list of split subnets if a new prefix was provided, plus payment metadata indicating charge status and transaction info.
Example use cases
Subnet planning for cloud VPC
“I'm setting up a VPC with the block 172.16.0.0/16 — can you split it into /24 subnets and tell me the total number of hosts, network address, and range?”
Firewall rule validation
“I need to know if the IP 192.168.5.200 falls within the subnet 192.168.5.0/26 — can you check that for me?”
Network audit of CIDR block
“Give me the full details for the CIDR block 203.0.113.0/28 — I need the netmask, wildcard mask, usable IP range, subnet size, and whether it's a private or public range.”
Technical details
Endpoint
GEThttps://tools.moneytools.dev/v1/ip-cidr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise, programmatic IPv4 or IPv6 subnet math — especially network/broadcast address computation, host count, netmask/wildcard derivation, private/reserved classification, IP membership checks, or CIDR splitting — rather than a general networking lookup or DNS resolution service. Ideal for infrastructure automation, firewall rule generation, and network planning workflows that require structured JSON output.
Side effects
- Invalid or malformed CIDR notation returns an error (not charged)
- Split prefix length smaller than or equal to input prefix length returns an error
- Contains IP outside valid format returns a parse error
- Free tier exhausted (10/day) without payment credentials returns 402 Payment Required
- Network errors or timeouts result in no charge
