With the rapid development of the Internet today, friends who often surf the Internet may have heard the terms static IP, dynamic IP , ADSL dial-up and DNS, but many people still can’t tell the difference between them. IP editor here Let me summarize.
1. What is static IP Internet access?
Static IP Internet access, also called fixed IP address Internet access: In this Internet access method, broadband operators will provide users with an IP address , subnet mask, gateway, and DNS server address. When the router is not in use, you only need to connect the home network cable to the computer and manually set the IP address on the computer so that the computer can access the Internet;
2. What is dynamic IP Internet access?
Dynamic IP Internet access, also known as DHCP Internet access: Automatically obtain IP for Internet access . Dynamic IP is a way of surfing the Internet, when the router is not used, just connect the broadband network cable to the computer, and set the IP address on the computer to automatically obtain, and the computer can go online;
3. What is ADSL dial-up Internet access?
ADSL dial-up Internet access, also called broadband dial-up Internet access: In this Internet access method, the broadband operator will assign a broadband account and broadband password to the user; in the case of not using a router, the computer needs to use the "broadband connection" dial-up to achieve Internet access. At present, due to the shortage of IP resources, major operators are gradually reducing this dial type;
4. What is DNS?
The domain name management system DNS (Domain Name System) means domain name resolution server. Its role on the Internet is to convert domain names into IP addresses that the network can recognize. For example, if we enter iphai.cn when surfing the Internet, it will be resolved to the server with IP 153.37.xx.xx.
The above is all, I hope it can help you understand the differences between these.
