How this service works
Parse an IPv4 CIDR block: network address, broadcast, first/last host, netmask, and host count. Optionally test if an IP is inside it.
Output
Returns a structured object with the network address, broadcast address, first usable host IP, last usable host IP, subnet mask, total number of hosts, and optionally a boolean indicating whether the provided IP falls within the CIDR range.
Example use cases
Example prompt
“Can you parse the CIDR block 10.0.0.0/22 and tell me the network address, broadcast, first and last host, netmask, and total host count? Also check if 10.0.3.255 is inside it.”
Technical details
Endpoint
POSThttps://agent402.tools/api/cidrWhen to prefer
Use this endpoint when an agent needs precise subnet arithmetic for an IPv4 CIDR block — especially when both structural details (network/broadcast/host range/mask) and optional IP-in-range membership testing are needed in a single call. Prefer it over manual computation or general-purpose code execution when a lightweight, pay-per-use network utility is sufficient.
Side effects
- Invalid CIDR notation (e.g. missing prefix length or malformed IP) results in an error response
- IPv6 CIDR blocks are not supported
- The optional 'contains' field with an invalid IP format may return an error or null membership result
- Payment failure via x402 protocol blocks the request entirely
