13.4 Definition of DNS Records
The built-in DNS Server functionality of Peplink Balance facilitates inbound load balancing. With the
presence of the functionality, NS/SOA DNS records for a domain name can be delegated to Internet IP
address(es) of Peplink Balance. Upon receiving a DNS query, Peplink Balance supports returning, as an
“A” record, the corresponding IP address for the domain name on the most appropriate healthy WAN
connection. It also supports acting as a generic DNS server for hosting “A”, “CNAME”, “MX”, “TXT” and
“NS” records.
(This example is for illustration only; the actual resolution that takes place in implementation will likely be
different.)
For example:
The DNS resolution of the domain name www.mycompany.com is delegated to the WAN2 Internet IP
addresses of Peplink Balance.
Upon receiving the DNS query, Peplink Balance returns, as an “A” record, the IP address for
www.mycompany.com on WAN1 because WAN1 is the most appropriate healthy link.
The settings for defining the DNS records to be hosted by Peplink Balance are located at: Network >
Inbound Access > DNS Settings
