24K Labs IP CIDR Calculator
x402
24K Labs IP CIDR Calculator is a paid API for AI agents from api.24klabs.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).
Performs CIDR math for IPv4/IPv6 addresses: computes network, broadcast, netmask, wildcard, prefix, usable host range and count, supports mask-to-prefix conversion, optional contains check, and subnet splitting.

How this service works
CIDR math for IPv4/IPv6: network, broadcast, netmask, wildcard, prefix, usable host range and count, mask<->prefix, plus optional contains check and subnet split.
Output
Returns a structured object containing: network address, broadcast address, netmask, wildcard mask, prefix length, first and last usable host IPs, total usable host count. Optionally includes a boolean result for whether a given IP is contained in the network, and an array of subnet CIDR blocks if a split was requested.
Example use cases
Subnet planning for a new VPC
“I'm setting up a new VPC with the block 172.16.0.0/20 — can you tell me the network address, broadcast address, netmask, wildcard, and how many usable hosts that gives me?”
Check if IP belongs to subnet
“I need to know if the IP 192.168.10.45 falls inside the network 192.168.10.0/26 — can you check that and also give me the full subnet details?”
Split a network into smaller subnets
“Take the network 10.100.0.0/16 and split it into 8 equal subnets — show me all the resulting CIDR blocks with their ranges.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/ip-cidr-calcWhen to prefer
Use this endpoint when you need precise, programmatic CIDR subnet calculations without setting up a local library — especially useful in network automation, infrastructure provisioning scripts, or agent workflows that need to validate IP ranges, plan address space, or check containment. Prefer this over general-purpose code execution when the goal is pure CIDR math with reliable structured output.
Side effects
- Invalid CIDR notation returns an error (e.g. missing prefix length or malformed IP)
- Prefix length out of range (e.g. /33 for IPv4) returns validation error
- IP version mismatch between CIDR and contains-check IP returns error
- Requesting too many subnet splits (e.g. splitting /30 into 64 subnets) may return an error or empty result
- Malformed request body returns 400-level error
