## What is Celnor?

Celnor – Network Guide is a practical troubleshooting companion for understanding common home network problems step by step. Start with the symptom you are seeing, answer a few guided questions, and follow a structured path toward the next useful check. Interactive troubleshooting guides cover connection problems, DNS-related issues, unstable connectivity, and other everyday network situations without making automatic configuration changes. Celnor is designed to remain useful even when your internet connection is unavailable, with guides and calculators that work offline. Use the Subnet Membership Calculator to check whether two IPv4 addresses belong to the same subnet and view their network addresses and subnet mask. The DNS Record Syntax Checker reviews the structure of A, AAAA, MX, TXT, and CNAME records for common formatting issues without performing live DNS queries. An MTU Payload Calculator helps estimate available payload size for IPv4 or IPv6 with ICMP, UDP, or TCP and shows the header breakdown behind the result. You can restart a guide, go back when an observation changes, or continue your current troubleshooting session from the home screen. Celnor focuses on helping you observe, compare, and reason through network problems instead of presenting unexplained technical data. The app provides manual guidance and local calculations only and does not scan, test, repair, or modify your network automatically.
