🧮 gateway calculator ip

Quickly find the correct gateway IP address for any subnet or IP range. Simplify your network configuration.

🌐 What is Jodie’s Gateway IP Calculator?

Jodie’s Gateway IP Calculator is a simple yet powerful tool designed to calculate the default gateway IP address based on a given IP address and subnet mask or CIDR notation. The gateway IP typically serves as the router’s address within a network—crucial for proper routing and communication between devices inside and outside the subnet.

Whether you’re setting up a home network or managing enterprise infrastructure, this calculator helps identify the right gateway IP to ensure smooth network operations.

✅ Why Use This Calculator?

• ⚡ Instant Gateway IP Calculation – Get the default gateway IP without guesswork.
• 🧠 Supports Multiple Formats – Enter IPs with subnet masks or CIDR notation (192.168.1.10/24).
• 🛠️ Avoid Network Misconfigurations – Ensure your gateway is correctly set within the subnet.
• 📚 Learn Networking Basics – Understand how gateways relate to IP ranges and subnetting.
• 💻 Save Time – Perfect for network admins, engineers, and students.

🛠️ How to Use Jodie’s Gateway IP Calculator

1. Enter the IP Address: Example — 192.168.1.15
2. Enter the Subnet Mask or CIDR: Example — 255.255.255.0 or /24
3. Click “Calculate”

The calculator will display:

• Network Address
• Broadcast Address
• Default Gateway IP (usually the first usable IP in the subnet)
• Usable IP Range
• Subnet Mask & CIDR Notation
