28. ternet There are two following methods to solve this problem Apply to buy a fixed IP address from the Telecom or Internet operators the fee will be higher Use the dynamic domain name resolution DDNS you can apply for a free or paid domain name from dynamic domain name service provider then use domain name instead of IP address so that regardless of changes in IP address domain name will point to IP addresses in real time like as we usually visit the website Some providers such as Changeip com and other dynamic domain name DDNS service providers offer free and paid dynamic domain name service you can consult them for their dynamic domain name service and charges issue Firstly you need to apply a dynamic domain from DNS service provider and download the Dynamic DNS client software run this software on the host of Server mode PC or router with DNS function After the client software has been successfully started Server host has solved the problem of dynamic IP address Input the dynamic domain name in the IP input box of Client remote host set the DNS server IP address as the local DNS server IP addresses then you can use the dynamic domain name to visit the internet In the following example use our free dynamic domain name kollew changeip com use the PC in Server side and run the dynamic domain name client software you can also use a router with the function of dynamic domain name DO a 1 PC work as Server ETH Adapt
