Networking

• Physical Network:
  • We use cables/medium to connect systems.
• Virtual Network:
  • This is software defined network used to connect virtual machines
    
• Ip address:
  • A unique number used to identify a system in a network
  • Network interface connects system to network and gets an ip address
    

IP Address

• Execute ipconfig

ip address       :  192.168.0.11
subnet mask      :  255.255.255.0
default gateway  :  192.168.0.1

• IP Address = Network id + host id
• Subnet mask helps in identifying network id and host id from ip address
  
• IP address format which we are looking into is IPv4.
• IP-address is 32 bit number and each position is an octet (8 bits) and 4 octets
• ip v4 range => 0.0.0.0 to 255.255.255.255
• Two systems can communicate with each other if they belong to same network
