Address(es)
returned when the Peplink Balance responds to DNS queries for the domain name specified
by Host Name.
The IP addresses listed in each box as default are the Internet IP addresses associated with
each of the WAN connections. Static IP addresses that are not associated with any WAN can
be entered into the Custom IP list. A PTR record is also created for each custom IP.
For WAN connections that operate under drop-in mode, there may be other routable IP
addresses in addition to the default IP address. Therefore, the Peplink Balance allows custom
Internet IP addresses to be added manually via filling the text box on the right-hand side and
clicking the button.
Only the checked IP addresses in the lists are candidates to be returned when responding to
a DNS query.
If a WAN connection is down, the corresponding set of IP addresses will not be returned.
However, the IP addresses in the Custom IP Address field will always be returned.
If the Connection Priority field is set to Custom, you can also specify the usage priority of
each WAN connection. Only selected IP address(es) of available connection(s) with the
highest priority, and custom IP addresses will be returned. By default, Connection Priority
is set to Default.
PTRRecords
PTR records are created along with A records pointing to custom IPs. For example, if you created an A
record www.mydomain.com pointing to 11.22.33.44, then a PTR record 44.33.22.11.in-addr.arpa pointing
to www.mydomain.com will also be created. When there are multiple host names pointing to the same IP
address, only one PTR record for the IP address will be created. In order for PTR records to function, you
also need to create NS records. For example, if the IP address range 11.22.33.0 to 11.22.33.255 is
delegated to the DNS server on the Peplink Balance, you will also have to create a domain 33.22.11.in-
addr.arpa and have its NS records pointing to your DNS server’s (the Peplink Balance’s) public IP
addresses. With the above records created, the PTR record creation is complete.

This table shows the TXT record of the domain name.
