Intelligent DNS resolution is a kind of DNS solution for the current problems of telecommunication and netcom interconnection. Concrete implementation is: the same domain name such as test.winiis.com of a record set points to netcom and telecom IP, when Netcom's customer access, smart DNS will automatically judge visitors routing, and return to the IP address of the Netcom server; Telecom customers will automatically return to the IP address of Telecom.

In this way, we can avoid Netcom's customers to visit the network of telecommunications, as well as telecom customers to visit the network of Netcom, a good solution to the problem of customers across the network access is not smooth. Of course, can also add multiple IP, by intelligent DNS Automatic "route", the same line IP address can do load balancing, downtime detection and other functions.

For example, Wddns Smart DNS will automatically judge the user's Internet line is netcom or telecommunications, and then intelligent return to the network or telecom server IP.

New generation of intelligent DNS such as Wddns multi-line and multiple area intelligent DNS, currently supports telecommunications/netcom/blind Network/Mobile/Tietong/Radio/Television/Provincial analysis (31 provinces)/search engine spiders and other multiple lines, with a strong monitoring function, server health detection

At the same time, a new generation of intelligent DNS, such as Wddns, load balancing, downtime processing, if the server down, the next generation of intelligent DNS can detect the real-time outage server IP, and the DNS resolution request to a functioning server. Thus providing a highly reliable and never downtime service.

The advent of intelligent DNS, the traditional each domain name corresponding to a mirror of the practice (such as ns1.wdlinux.cn to telecommunications, ns2.wdlinux.cn to Netcom), so that users more fool to visit the site.
