Description

Library can get various network information about domain names and IP-addresses.

Currently it provides the following information:

• whois (currently using node-whois library)
• BGP information (AS number and name)
• define whether IP address is TOR node either exit node, or entry node, or other
• DNS information
• GeoLocation information simultaneously using MaxMind and IP2Location databases

Installation

You can install it with this command:

npm install node-xwhois

Usage

Simplest way to get all possible information about domain name or IP address is using hostInfo() function:

'use strict'
const whois = require('node-xwhois');

const host1 = 'xinit.ru';
const host2 = '8.8.8.8';

whois.geoInit('test/GeoIP')
.then(() => {
    whois.hostInfo(host1)
    .then(data => console.log(`${host1} info:\n`, JSON.stringify(data, null, 4)))
    .catch(err => console.log(err));

    whois.hostInfo(host2)
    .then(data => console.log(`${host2} info:\n`, JSON.stringify(data, null, 4)))
    .catch(err => console.log(err));
})
.catch(err => console.log(err));

All asynchronous functions in this library return Promises.

ip2long(ip)

A JavaScript equivalent of PHP's ip2long(). Convert IPv4 address in dotted notation to 32-bit long integer. You can pass IP in all possible representations, i.e.:

192.0.34.166
0xC0.0x00.0x02.0xEB
0xC00002EB
3221226219
0.0xABCDEF
255.255.255.256
0300.0000.0002.0353
030000001353

Parameters

ip String. IPv4-address in one of possible representations.

Return

32-bit number notation of IP-address expressed in decimal.

isIP(host)

Detect if host is correct IP-address. Internally uses net.isIP().

Parameters

host String to test.

Return

true if host is correct IP address or false otherwise.

isDomain(host)

Detect if host is correct domain name. It can't test IDN's. And it can't define if domain name is really exist or can exist. This function just performs syntax check.

Parameters

host String to test.

Return

True if host is correct domain name false otherwise.

reverse(ip)

Define domain names by IP-address using reverse domain request.

Parameters

ip IP-address to reverse.

Return

Promise where then() takes function with array of hostnames.

Example

const host = '8.8.8.8';

whois.reverse(host)
.then(hostnames => console.log(`${host} reverse:\n`, JSON.stringify(hostnames, null, 4)))
.catch(err => console.log(err));

nslookup(host)

Get host info of domain name like host -a command.

Parameters

host Domain name.

Return

Promise where then() takes function with object like this:

{
    'A'    : ['IPv4-addresses'],
    'AAAA' : ['IPv6-addresses'],
    'MX'   : ['MX-records'    ],
    'TXT'  : ['TXT-records'   ],
    'SRV'  : ['SRV-records'   ],
    'NS'   : ['NS-records'    ],
    'CNAME': ['CNAME-records' ],
    'SOA'  : ['SOA-records'   ]
}

Example

const host = 'xinit.co';

whois.nslookup(host)
.then(info => console.log(`${host} nslookup:\n`, JSON.stringify(info, null, 4)))
.catch(err => console.log(err));

whois(host)

Perform whois request.

Parameters

host Domain name or IP-address.

Return

Promise where then() takes function with whois text.

Example

const host = 'xinit.co';

whois.whois(host)
.then(info => console.log(`${host} whois:\n`, JSON.stringify(info, null, 4)))
.catch(err => console.log(err));

torInfo(ip)

Check if IP address is a TOR node.

Parameters

ip IP-address.

Return

Promise where then() takes function with object like this:

{
    'nodename': 'Name of TOR node',
    'port'    : [0, 0],  // port numbers of TOR node
    'exitNode': true     // if true then this is exit node
}

If IP does not belong to TOR node then null will be passed instead of described object.

Example

const host = '199.87.154.255';

whois.torInfo(host)
.then(info => console.log(`${host} torInfo:\n`, JSON.stringify(info, null, 4)))
.catch(err => console.log(err));

extractIP(str)

Extract IP-addresses from raw text. If some IP-address appears in str multiple times then it will be returned in answer only once.

Parameters

str String to extract IP-addresses from.

Return

Promise where then() takes function with array of IP-addresses as strings.

Example

const ipStr = `
    test raw text test raw text
    77.109.141.140    (37.187.130.68)   ++   188.40.143.7   $$   95.174.227.96 test raw text
    test raw text test raw text test raw text test raw text
    2001:0db8:11a3:09d7:1f34:8a2e:07a0:765d    test raw text test raw text

.then(info => console.log('extractIP:\n', JSON.stringify(info, null, 4)))
.catch(err => console.log(err));
