Working on Smart DNS
The below diagram describes the working of Smart DNS. It consists of various networking components such as server, DNS, and proxy.
- Smart DNS servers receives the DNS requests from the clients and provides the DNS responses to the servers that are situated at different geographical regions according to the users choice.
- While using Smart DNS service, the device firs sends the request to Smart DNS server first and then sends it to the regular DNS server.
- Upon receiving the request the Smart DNS server checks whether the domain name is associated with the geo-restricted service or not.
- If this domain name is associated with the geo-restricted service, the IP address of proxy server is returned by the Smart DNS server. This IP address is of proxy server where services are not blocked.
- The proxy server then forwards the request received from Smart DNS server to the blocked service and the content will become unblocked.
What is Smart DNS?
DNS stands for Domain Name System. Each network consists of multiple networking devices. Every device can be identified with the help of a unique IP address given for each device. DNS is used to translate the domain name into IP addresses. When a user searches for a domain name initially it is sent to the DNS server. The DNS server then returns the IP address for that domain name. Smart DNS provides more features than DNS. The below article covers this in detail regarding Smart DNS.
