What is ddns? What is the purpose? How to Use nat123 dynamic domain name resolution?
Ddns is dynamic domain name resolutionTo solve the problem of dynamic public IP address and obtain real-time public IP address information.
For how to use
Ros use ADSL, each dial-up IP will change, resulting in external network access to the ROS server failure, the most common solution is to use DDNS Dynamic Domain tool, after dialing (IP changes) notify the DDNS server update IP, This server can be permanently accessed using the static domain name provided by the DDNS service provider. ROS officials only support C
There is a router in the home that uses the old Mozie firmware (Padavan). In order to be able to access the router in the company, or the home computer, you need to configure a dynamic Domain name resolution (DDNS) for the router. The following steps are described.1, apply for dynamic domain name Here I use the peanut shell dynamic Domain name resolution. First, apply for a dynamic domain name (for example: hangge.oicp.net) on the official website.
Problem Description: The client is a dynamic IP, after each network to Nsupdate to the client's hostname and IP map to update to the DNS serverThe command is as follows: Nsupdate-k k*****.

DDNS principle: DNS + DHCP =ddns
DHCP is responsible for IP resolution, and is assigned to client IP,IP as a random number.
DNS is responsible for domain name resolution, a record of each IP corresponding domain name.
Client IP is definitely changing, it is not possible to always use an IP, so when the client's IP change, using the DDNS service, while notifyin
