Does the Device Support DNS Proxy?

Does the Device Support DNS Proxy?

The device supports DNS proxy. The DNS proxy forwards DNS request and response packets between a DNS client and DNS server. The DNS client on a LAN considers the DNS proxy as the DNS server and sends DNS request packets to the DNS proxy. The DNS proxy forwards DNS request packets to the DNS server, and sends DNS response packets from the DNS server to the DNS client, to implement domain name resolution. When the DNS server's IP address changes, you only need to change the DNS proxy configuration without changing the configuration of each DNS client. This simplifies network management.
