Win7 system relies on cool interface and simple, simple, When we use Win7, we sometimes encounter some network problems, and we need to check or set the network IP and DNS (Domain Name System) ourselves. Here we introduce the specific operation methods and steps.

click the "network connection sign" icon in the lower right corner of Win7 desktop with the right mouse button or the left mouse button, and select "Open the network and enjoy the center".

click "local connection" in "network and * * * enjoyment center".

in the "local connection status" panel, we can see the current network local connection status, and click the "Properties" button.

according to the current network situation, select "Internet protocol 4(TCP/IP)" or "Internet protocol 6(TCP/IP)". At present, most networks should be "Internet Protocol 4(TCP/IP)", and then click the "Properties" button to enter the setting interface.

now we have entered the current network IP and DNS setting interface of 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", and DHCP will automatically assign Internet protocol (IP) addresses to computers in the network without manual configuration.

if manual configuration is required, select "use the following IP address" and "use the following DNS server address", and then fill in the specific setting parameters.

note: DNS is the abbreviation of Domain Name System or Domain Name Service, which is composed of a parser and a domain name server. The domain name server stores domain names and corresponding IP addresses of all hosts in the network, and can convert domain names into IP addresses.

in IPV4, IP is composed of 32-bit binary numbers. Divide these 32-bit binary numbers into 4 groups with 8 binary numbers in each group, and convert these 8 binary numbers into decimal numbers, which is the IP address we see, and its range is between and 255. In IPV6 which will replace IPv4 in the future, an IP address will be represented by a 128-bit binary number.
