About the Network IP Calculator
The Network IP Calculator is a free, powerful online tool designed for Cisco network engineers and IT professionals to streamline IP subnet calculations and network configuration tasks. Supporting both IPv4 and IPv6, this tool offers advanced features like Cisco IOS configuration generation, subnet overlap detection, ACL creation, and supernet calculation, making it essential for network design, troubleshooting, and optimization.
Why Use Our IP Calculator?
Whether you're configuring Cisco routers, planning enterprise networks, or studying for CCNA/CCNP certifications, our calculator simplifies complex tasks. Key benefits include:
- Comprehensive Subnet Calculations: Instantly compute network addresses, broadcast addresses, usable host ranges, and more for IPv4 and IPv6.
- Cisco Integration: Generate ready-to-use Cisco IOS commands for interface and ACL configurations.
- Advanced Tools: Detect subnet overlaps, simulate pings, create network diagrams, and calculate supernets for BGP/OSPF optimization.
- User-Friendly: Intuitive interface with input history and example calculations for quick learning.
Features for Cisco Engineers
Our tool is tailored for Cisco environments, offering:
- Cisco IOS Config Generator: Automatically create commands for interface IP assignments and routing.
- ACL Generator: Build standard ACLs to secure your network with permit/deny rules.
- Subnet Overlap Checker: Ensure clean network designs by identifying conflicting subnets.
- Supernet Calculator: Optimize routing tables with route summarization for BGP and OSPF.
- Network Diagram Preview: Visualize subnet structures for documentation and planning.
- Ping Simulation: Test connectivity within subnets without network access.
How It Works
1. Input IP Details: Enter an IPv4 or IPv6 address and subnet mask/prefix length.
2. Select Calculation Type: Choose from subnet info, hosts needed, subnets needed, VLSM, overlap check, or supernet calculation.
3. View Results: Get detailed outputs, including Cisco configs, diagrams, and ACLs.
4. Save Time: Use input history and example calculations to speed up your workflow.
Applications
This tool is ideal for:
- Designing enterprise networks with Cisco devices.
- Troubleshooting IP conflicts and routing issues.
