🧮 Jodie’s CIDR Calculator IP Range
Instantly determine the IP range and subnet details from any CIDR notation. Perfect for network planning and troubleshooting.
🌐 What is Jodie’s CIDR Calculator?
Jodie’s CIDR Calculator is a handy tool that converts CIDR (Classless Inter-Domain Routing) notation—like /24, /28, or /16—into a full IP range along with essential subnet details. It simplifies network addressing by showing you the network address, broadcast address, usable host range, and total number of hosts based on any given CIDR.
Whether you’re managing a small office network or configuring large enterprise subnets, this tool takes the guesswork out of CIDR calculations.
✅ Why Use This Calculator?
- ⚡ Quick Conversion – Enter CIDR notation and instantly get the detailed IP range.
- 🧠 Accurate Subnet Information – Displays network and broadcast addresses, usable IP range, and subnet mask.
- 📚 Educational Tool – Helps students and professionals understand how CIDR defines IP blocks.
- 🔧 Simplifies Network Design – Plan subnets, DHCP scopes, and firewall rules with precision.
- 💻 Avoid Configuration Errors – Know exactly which IPs are usable within a subnet.
🛠️ How to Use Jodie’s CIDR Calculator
