🎯 IP Gateway Calculator: Find Your Network’s Gateway Address Easily

Setting up and managing networks requires knowing the correct gateway IP address. An IP Gateway Calculator helps you quickly determine the gateway address for any subnet, ensuring your devices communicate smoothly beyond the local network.

🔍 What Is an IP Gateway Calculator?

This tool takes your IP address and subnet mask or CIDR prefix and calculates the default gateway IP—usually the first usable IP address in the subnet—which acts as the exit point from your local network to other networks or the internet.

🛠️ How to Use an IP Gateway Calculator

Enter your IP Address (e.g., 192.168.1.45).
Enter your Subnet Mask (e.g., 255.255.255.0) or CIDR (e.g., /24).
Click Calculate.
See the calculated Gateway IP Address along with network details like network and broadcast addresses.

Subnet Mask: 255.255.252.0 (/22)
Network Address: 10.0.4.0
Broadcast Address: 10.0.7.255
Gateway IP Address: 10.0.4.1 (first usable IP in the subnet)

🚀 Tips for Using an IP Gateway Calculator

Confirm the gateway IP matches your router’s configured IP
Use the calculator when setting up new subnets or troubleshooting
Document gateway addresses for all subnets in your network
Combine with IP range and subnet calculators for full network insights
