Right-click or left-click on the "Network Connection Flag" icon in the lower right corner of the Win7 desktop and select "Open Network and Sharing Center".
Click "Local Area Connection" in "Network and Sharing Center".
In the "Local Area Connection Status" panel, we can see the current network local connection status, click the "Properties" button.
Select "Internet Protocol 4 (TCP/IP)" or "Internet Protocol 6 (TCP/IP)" according to the current network conditions. At present, most of the network should be "Internet Protocol 4 (TCP/IP)", and then click the "Properties" button to enter the settings interface.
Now we are in the current network IP and DNS settings interface of the Win7 system.
If the network supports DHCP (Automatic Dynamic Host Configuration Protocol), we can directly select "automatically obtain IP address" and "automatically obtain DNS server address", then DHCP will automatically allocate for computers in the network. Internet Protocol (IP) address, no manual configuration required.
If you need to manually configure, select "Use the following IP address" and "Use the following DNS server address", and then fill in the specific setting parameters.
Note: DNS is an abbreviation for Domain Name System or Domain Name Service, which consists of a resolver and a domain name server. The domain name server stores the domain name and corresponding IP address of all hosts in the network, and can convert the domain name into an IP address.
In IPV4, IP is composed of 32-bit binary numbers. The 32-bit binary number is divided into 4 groups of 8 binary numbers, and these 8 binary numbers are converted into decimal numbers. The IP address we see, the range is between 0 and 255. In IPV6, which replaces IPv4 in the future, an IP address will be represented by a 128-bit binary number.
