This page is designed to help you find out whether RouterNAT is good and if it is the right choice for you.
RouterNAT is a collection of free browser-based utilities for router owners, home-network users, technicians, and small-office administrators. The tools help users understand IP addressing, NAT behavior, subnetting, DHCP configuration, Wi-Fi performance, and common router problems without installing additional software.
The IP and NAT utilities include public IP detection, IP address lookup, address-type classification, CGNAT checking, and Double NAT diagnosis. These tools explain whether an address is public, private, shared, reserved, or potentially affected by an upstream translation layer.
Network-planning utilities include IPv4 subnet calculation, CIDR conversion, DHCP range validation, static IP reservation planning, and VLAN, SSID, and subnet organization. Results include practical explanations intended to reduce addressing conflicts and configuration mistakes.
RouterNAT also provides Wi-Fi tools for channel planning, coverage estimation, client-capacity planning, and repeater performance calculations. Additional utilities help users prepare for a router factory reset, evaluate password characteristics locally inside the browser, and review essential network settings.
Many calculations are performed directly inside the user’s browser. RouterNAT tools do not attempt to sign in to, scan, or modify routers and connected devices. They are intended for legitimate network education, planning, and troubleshooting.
Results may vary according to ISP architecture, router firmware, wireless conditions, and the values supplied by the user. Important network changes should be verified against the router manufacturer’s documentation, ISP instructions, or advice from an authorized network administrator.
RouterNAT also publishes original technical articles about NAT, CGNAT, router security, Wi-Fi performance, IP addressing, and practical home-network troubleshooting.

Responsive Interface
1. Works across desktop, tablet, and mobile browsers.
RouterNAT uses Go, PostgreSQL, server-rendered HTML, CSS, and lightweight JavaScript. It runs on Linux with Caddy providing HTTPS and reverse-proxy services.
The primary audience includes home router owners, Wi-Fi users, IT students, network technicians, small-office administrators, and people troubleshooting IP addressing, NAT, DHCP, subnetting, or wireless performance.
RouterNAT was created to make common router and network concepts easier to understand. Many existing tools provide a single number without explaining its meaning. RouterNAT combines useful calculations with practical guidance so users can make better-informed troubleshooting decisions.
RouterNAT combines practical networking calculators, diagnostic tools, and clear technical explanations in one lightweight website. Many calculations run directly inside the browser. The tools do not attempt to sign in to, scan, or modify routers and connected devices.
RouterNAT focuses specifically on problems faced by router owners, home-network users, and small-office administrators. Results include understandable explanations, limitations, and relevant troubleshooting guidance instead of returning unexplained values.
RouterNAT is a free public resource and does not claim named enterprise customers.
It is designed for individual router owners, home-network users, technicians, students, and small-office administrators.
