Sample addresses to figure out if a host + port is consistent
npm install nat-samplerSample addresses to figure out if a host + port is consistent
``
npm install nat-sampler
` js
const NatSampler = require('nat-sampler')
const s = new NatSampler()
// add a sample
const hits = s.add('127.0.0.1', 9090)
console.log('In there this many times:', hits)
console.log('Estimated host + port', s.host, s.port)
`
#### s = new NatSampler()
Make a new sampler.
#### hits = s.add(host, port)
Add a sample of your host and port.
Returns how many hits this entry has.
#### s.host
What the sampler thinks your host is.
If your host is unknown it will be null.
#### s.port
What the sampler thinks your port is.
If your port is random or unknown it will be 0.
#### s.size
How many samples the sampler is basing this on.
The sampler applies some simple error correction to make sure bad samples do not mess it up.
* If it has <= 3 samples, it will disregard none outliers.<=
* If it has 7 samples, it will disregard one outliers.<=
* If it has 11 samples, it will disregard two outliers.>
* If it has 11 samples, it will disregard three outliers.
At max it keeps 16 samples of { host, port }` pairs for the analysis.
