This utility does a basic validation of geofeed files. Geofeed files are used by Internet providers to provide geolocation information about their IP resources. The geofeed format is described in RFC8805.
If you want to correct/crowdsource the geolocation of your IP resources, you should link your geofeed file in whois data. You can do that by adding a "remark" in your "inetnum" object, such a remark must be in the format "Geofeed URL". See RFC9092 for instructions. In this case, instead of using geofeed-validator, you can use geofeed-finder to test the entire whois+geofeed setup.
To use the compiled version (linux, mac, windows), see releases.
Otherwise, you can just download the code and do npm install
and npm run serve
to run it.
You can run geofeed-validator
in the command line, to validate a geofeed file.
- Run the binary
./geofeed-validator-linux-x64 -f YOUR_GEOFEED_FILE
- Run the source code
npm run serve -- --f YOUR_GEOFEED_FILE
Install it:
npm install geofeed-validator
Import it:
import validator from "geofeed-validator";
Use it:
// From String
const errors = validator.fromLine("193.201.40.0/24,IT,IT-RM,Rome,");
//From Array
const errors = validator.fromArray(["193.201.40.0/24", "IT", "IT-RM", "Rome", null]);
// The "errors" array will contain strings describing the errors
// Such as: [ 'Not valid Subdivision Code (iso-3166-2)' ]
// If the array is empty, everything is fine
if (errors.length === 0) {
console.log("Everything is fine");
}
The example above shows how to validate a single geofeed line. If you want to validate an entire geofeed file, you can read the file line by line and validate each line. See example below.
const file = "YOUR_GEOFEED_FILE";
const rd = readline.createInterface({
input: fs.createReadStream(file),
console: false
});
rd.on('line', function(line) {
const errors = validator.fromLine(line);
if (errors.length) {
console.log(`${line} Error: ${errors.join(", ")}`);
}
});
