Please let me know if there is something wrong or unclear in this article. thank you! DDNS configuration instances (DHCP + DNSDDNS) are a basic task in network management. However, as the network grows, it will be very troublesome to frequently modify data files in the DNS region. Therefore, dynamic DNS came into being.

What is ddns network connection?According to statistics, for the vast majority of Enterprise leased line users, the total time for data flow on the leased line is no more than 8 hours. This means that a leased line user has to pay 2/3 of the time every day instead of using network resources. The price of leased lines remains high, so that ordinary enterprise users are discouraged. Therefore, the ideal way for enterprises to access the Internet is to a

What is DDNS?
I. Introduction to DDNS
The DNS and domain name system are a service of the Internet. As a distributed database that maps domain names and IP addresses to each other, it makes it easier for people to access the Internet.
DDNS, a dynamic domain name system, is a technology that automatically updates the name server content in the Domain Name Syste

DDNS principle: DNS + DHCP = DDNS
DHCP is responsible for ip resolution and allocation to the Client ip address. The ip address is a random number.
DNS is responsible for domain name resolution. The A record records the domain name corresponding to each ip address.
The Client ip address must be changed, and it is impossible to use an ip address all the time. Therefore, when the client ip address changes, th
