Subnet and CIDR Calculator

Calculate subnet masks, CIDR blocks and host ranges offline for IPv4 and IPv6. Get the netmask, wildcard mask, network and broadcast address, first and last usable host, and address counts. Split networks into subnets, list hosts, test if an IP is in range, or turn an IP range into CIDR blocks.

Subnet and CIDR Calculator - IP Ranges and Netmasks OpenAPI definition

OpenAPI is a standard for designing and describing RESTful APIs, allowing developers to define API structure, endpoints, and data formats in a machine-readable way. It simplifies API development, integration, and documentation.

OpenAPI is effective when used with AI agents and GPTs by standardizing how these systems interact with various APIs, for reliable integrations and efficient communication.

By defining machine-readable API specifications, OpenAPI allows AI models like GPTs to understand and use varied data sources, improving accuracy. This accelerates development, reduces errors, and provides context-aware responses, making OpenAPI a core component for AI applications.

You can download the OpenAPI definitions for Subnet and CIDR Calculator from the options below:

OpenAPI.json
