About TelcoAIO

TelcoAIO is a bilingual static toolbox for telecom and network engineering workflows. It focuses on practical browser-based utilities for subnet planning, routing analysis, DNS checks, prefix validation, and maintenance communications without requiring accounts, plugins, or a heavy backend.

Why It Exists

The project started from a simple operational problem: many day-to-day checks in network work are small, repetitive, and scattered across different tools. A subnet task might live in one place, a routing check in another, an RPKI lookup somewhere else, and maintenance wording in a document template that has to be rebuilt every time. TelcoAIO tries to reduce that switching cost by keeping related tasks under one lightweight roof.

How It Works

Some tools are pure browser-side utilities, such as subnetting, MTU overhead modelling, and route-filter generation. Others depend on public upstream data sources, including RIPEstat, the RIPE Database, Google Public DNS, and Cloudflare DNS. Where external data is involved, the goal is to make those dependencies clear instead of pretending the site owns the underlying data.

What It Is And Is Not

TelcoAIO is meant to be a practical operator aid. It is not a replacement for vendor documentation, peering contracts, internal observability, or a production change process. If a result will affect a live routing decision or customer communication, it should be checked against the authoritative source before you act on it.

Maintainer

TelcoAIO is maintained by Ray as a personal project. The public code repository is github.com/crusaderay/telcoaio. That means the site is intentionally small, opinionated, and shaped by real network operations use cases rather than by a broad product team.
