Model

Every Protocol instance meet this model:

{
  Hex: string;
  Number: number;
  Name: string;
  Description: string;
}

Using

Specific protocols

import { ICMP, UDP } from 'ip-protocols';

const myProtocol = 17;
const isMyProtocolICMP = ICMP.Number === myProtocol; // false
const isMyProtocolUDP = UDP.Number === myProtocol; // true

console.log(ICMP);

/* Output:
{
  Hex: '0x01',
  Number: 1,
  Name: 'ICMP',
  Description: 'Internet Control Message Protocol'
}
*/

Searching methods

import { findByNumber } from 'ip-protocols';

const protocol = findByNumber(6);

console.log(protocol);

/* Output:
{
  Hex: '0x06',
  Number: 6,
  Name: 'TCP',
  Description: 'Transmission Control Protocol'
}
*/

findByName - is case-insensitive

import { findByName } from 'ip-protocols';

const protocol = findByName('uDp');

console.log(protocol);

/* Output:
{
  Hex: '0x11',
  Number: 17,
  Name: 'UDP',
  Description: 'User Datagram Protocol'
}
*/

findByHex

import { findByHex } from 'ip-protocols';

const protocol = findByHex('0x3C');

console.log(protocol);

/* Output:
{
  Hex: '0x3C',
  Number: 60,
  Name: 'IPv6-Opts',
  Description: 'Destination Options for IPv6'
}
*/

General array

import { protocolList } from 'ip-protocols';

const pr1 = protocolList[120];
const pr2 = protocolList[44];
const pr3 = protocolList[78];

console.log(pr1);
console.log(pr2);
console.log(pr3);

/* Output:
{
  Hex: '0x78',
  Number: 120,
  Name: 'UTI',
  Description: 'Universal Transport Interface Protocol'
}
{
  Hex: '0x2C',
  Number: 44,
  Name: 'IPv6-Frag',
  Description: 'Fragment Header for IPv6'
}
{
  Hex: '0x4E',
  Number: 78,
  Name: 'WB-MON',
  Description: 'WIDEBAND Monitoring'
}
