To simplify network management, you can use the DNS proxyfunction.As shown in Figure 37:• Specify Device A as the DNS server of Device B (the DNS client). Device A acts as a DNS proxy.The IPv6 address of the real DNS server is 4.1.1.1.• Configure the IP address of the DNS proxy on Device B. DNS requests of Device B are forwardedto the real DNS server through the DNS proxy.
