DNS (Domain Name System) is a naming system that facilitates the exchange of data between computers over the Internet and other networks. Its main function is to translate user-friendly domain names (e.g. www.synology.com) into corresponding fixed, public IP addresses (e.g. 120.89.71.100). This function allows users to easily find web pages, computers, or other devices over the Internet or local network.
DNS Server allows your Synology Router to become a domain name server, host multiple zones, as well as provide name and IP address resolution services.
Please see the following notes before using DNS Server:
Manage your domains and resource records, including Host (A), Alias (CNAME), and Mail Exchange (MX) records, and map domain names to the IP addresses of your computers or devices.
Allow clients to query domains for which your Synology Router is not authoritative by enabling recursive resolution, limiting service hosts, and designating forwarders.
View and manage information related to past DNS activity.
Limit access to zone files by creating and managing TSIG (Transfer Signature) keys.
Provide services for different groups by creating multiple views.
Edit DNS settings according to your individual environment.
