IP ADDRESS DETECTION

  

Yourself: From ISP Public IP.

   From local router to access internet: Public and private

   From Local router to access local network: Private IP

   

   Linux: ifconfig

        Router: ipr

  NMap stands for network mapper. Used for network scanning.

  USES: Ping Sweeping

        Running service detection

        Open ports 

        Check target connectivity by firewall bypassing

        Mac address detection

        DOS Attack


  NMap Command commands:

# Default scan: It will result the following 

                Host Status <up/down>

                Target mac address detection

                Open ports

                Protocol used <TCP/UDP>

                Port Status <Open/Closed/Filtered>

                Running services name on open ports

  Commands: nmap <target ip>

            nmap <target domain>

            

# Default scan + firewall bypassing

          : nmap -Pn <target ip>

# Quick fastscan: It will result Host status <up/down>

Mac address: nmap -sP <target ip>

# Target os detection :It will result Default scan + OS

          : nmap -O <target ip>

#All detail Scan: It will result Default scan + Os detection + Root trace

          : nmap -A <target ip>


# Port scanning: 

  Scanning a specific port :

          : nmap -p <port number> <target Ip>

  scanning port in a range:  

          : nmap -p <starting port> - <ending port>

  Scanning port all 65535:

          : nmap -p- <target ip>


* Ping Sweep: Process of bulk sweep

   Firewall detection steps:

   Ping

   nmap -Pn <target ip>

   Angry ip scanner

Ports

Port  Port scanning: in computing device a port is like a door which is used in data transmission and other services like charging, running a service-application etc. A port provides interface between two devices to send and receive information/data. Types of ports:-              # Physical ports: also known as hardware port and external ports: ex, usb, type-c, micro usb,                        rj45lan, HDMI, vga, SD card port thunderbolt, audio-3.O etc.              # Virtual ports: also known as pcp and udp ports internal ports, application port we have total                     65535 virtual ports in our computing devices. > total no. of ports  = 65535 > range = 0-65534 # top 1024 (0-1023) ports known as predefined virtual ports/ fixed virtual ports/ reserved virtual ports. #1024-65534 ...

  NETWORK  A computer network is a group of two or more computer system linked together, collection of machine devices, computer, mobile, notes, servers, etc. * Lan: (Local area network) uses private/in a limited range (WIFI, Bluetooth). * Man: (Metropolitan area network) uses publics/city/state (limited area) network. Ex. cable tv operator,   broadband connection, landline connection. * Wan: (Wide area network) uses public, entire world, group of countries, internet access through   satellite. * Pan: (Personal Area Network)    It is a unique identification address in a network for each connected device. Types of IP address: (Uses, versions and allocation) * Allocation: Static is fix does not change. Dynamic is a continuous process. * Versions of IP address:    There are two versions of IP: i IPV4: Internet protocol version 4   Properties of IPV4:   Size- It is a 32 bit address.   No. of blocks: It consist of 4 blocks...

  FOOTPRINTING =>  Footprinting is the first step of hacking. it is the process of collecting as much information as possible about the target. Attackers gathers publicly  available sensitive information using which he/she performs social engineering, network and system attacks.    Why perform Footprinting? =  Footprinting is about gathering info and formulating hacking strategy. As a hackers you may be able to uncover the path of least resistance on target expect to obtain information as follows:-     Information about target security posture and where potential loop holes may exist.    A database that points detailed picture with maximum amount of information possible about target.
