Overview

Typically, a DNS server returns the same resolution result to visitors from different networks or geographic locations. However, in case of cross-network or cross-region access, this would lead to long latency and poor user experience.

With configurable resolution lines, you can specify that the DNS server return different resolution results for the same domain name based on the networks or geographic locations of visitors' IP addresses.

In addition to ISP and region lines, the DNS service allows you to define resolution lines based on IP address ranges to route visitors to different web servers.

For a website deployed on multiple servers, you can set different weights for the record sets to balance the loads of these servers.

Table 1 describes the scenarios and operations for configuring resolution lines.
