How accurate is IP geolocation?

City accuracy for fixed-line broadband, roughly 50-100 km. Much worse for mobile and corporate IPs. It is a heuristic based on the ISP's registered address ranges, not a real location signal. Never rely on it for security decisions.

Why does the weather show a different temperature to my window?

Weather models compute city-level averages, usually anchored to the nearest official weather station (often an airport). Micro-climates, urban heat-island effects and elevation changes within a city easily produce 2-4°C differences from your actual location. For your street, a local sensor beats any national forecast.

Which AQI scale is reported?

The European AQI, which uses PM2.5, PM10, NO₂ and O₃ concentrations with EU-specified breakpoints. The raw PM2.5 and PM10 values are also displayed so you can compare against the US EPA scale, the Indian NAQI, or your country's own scale if it differs.

Network & Web

Two focused network lookups: your public IP address with approximate geolocation and ISP name, and current weather plus air-quality readings (temperature, humidity, wind, AQI, PM2.5, PM10) for any city in the world.

About network & web on Dailiyo

The network category is deliberately small. Where a lookup needs a fresh network round-trip (as opposed to maths in your browser), we surface the specific public API the tool calls so you can see where the request goes. IP geolocation uses ipapi; weather and air quality use Open-Meteo — both are free public APIs with clear privacy policies that do not require an account and do not fingerprint the caller.

IP geolocation is approximate by nature. A residential IP from a UK broadband ISP is usually accurate to city level (roughly 50-100 km). A mobile IP from a large carrier may report a location hundreds of kilometres from the actual device because the IP is assigned to the carrier's regional gateway, not the tower. A corporate IP might report the head-office city regardless of where the employee actually is. Never use IP geolocation for anything security-critical; use it for casual curiosity, timezone detection, or as one signal among many.

Weather and air-quality data come from Open-Meteo's aggregation of national meteorological services (ECMWF, NOAA, DWD, etc.) and satellite-derived air-quality models. For everyday travel and outdoor-activity planning it is accurate and useful; for safety-critical decisions (aviation, offshore, wildfire response) use your national forecast agency directly (Met Office in the UK, NWS in the US, JMA in Japan, and so on). The AQI scale we report is the European AQI; if you want the US EPA scale or a country-specific scale, cross-check with your national environment agency.
