• IPV4 : The identity used to target the host. 32bit is divided into the network part and the host part. Usually paired with the subnet mask appears.
• Subnet mask : Used to determine the portion of the network in the IP address ( 1 in binary).
• ARP: The IP address of the target host to obtain its MAC address for data communication. Note : Used between the same network segment
• routers : or gateways, used for addressing between different network segments. Usually you need to maintain a routing table

• Domain name : Because of the way the IP address is difficult to remember, so the domain name of the way the host is marked.

  www.google.com: where www is the hostname, the other host name can be ftp,maiL and other commonly used to indicate the host server name;Google is the domain; . NET is type

• DNS: Each domain name corresponds to an IP address, so the task of resolving the domain name to IP requires the DNS service to complete

So

If you want to configure your computer for network configuration, you need this

• Configuring a LAN Communication computer

  • IP Address
  • Subnet mask

• Configuring a cross-network communication computer

  • IP Address
  • Subnet mask
  • Gateway

• Configure a communication computer that can be connected to the Internet

  • IP Address
  • Subnet mask
  • Gateway
  • Dns
