How this service works
Split an IPv4 CIDR block into subnets by new prefix or subnet count - network, broadcast, first and last host and usable hosts for each subnet
Output
Returns a JSON object containing the parent CIDR, new prefix, subnet mask, total subnet count, addresses per subnet, usable hosts per subnet, and an array of subnets each with its CIDR, network address, broadcast address (null for /31 and /32), first host, last host, and usable host count. May include a truncated flag and shown count if the result set is large.
Example use cases
Data center VLAN planning
“I need to divide 172.16.0.0/20 into /26 subnets for our office VLANs — can you list every subnet with its network address, broadcast address, first and last usable host?”
Cloud VPC subnet allocation
“We're setting up a VPC with the block 10.100.0.0/22 and want to break it into /24 subnets — show me all the subnets including usable host counts.”
Teaching IP subnetting
“Split 192.168.1.0/24 into /28 subnets and list the network, broadcast, and usable host range for each so I can use it as a classroom example.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/net/subnet-split?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically enumerate all subnets produced by splitting a given IPv4 CIDR block, including full host range details for each subnet. It is ideal for network planning, infrastructure automation, IP address management (IPAM) workflows, and educational tooling. Prefer it over a generic subnet calculator when you need structured JSON output ready for agent consumption at low per-call cost.
Side effects
- Invalid CIDR notation (e.g. missing prefix, out-of-range octets) returns an error
- New prefix shorter than or equal to parent prefix (would produce 0 or 1 subnets) may return an error or unexpected result
- Missing required query parameters (cidr or new_prefix) returns a 400-level error
- Very large splits (e.g. /8 into /30) may return a truncated list with truncated=true
- Non-IPv4 input (e.g. IPv6 CIDR) is not supported
