recovery, this value should be set to a smaller value, e.g., 5 secs, 60 secs, etc.
Priority
This option specifies the priority of different connections.
Select the Default option to apply the Default Connection Priority (refer to the table
shown on the main DNS settings page) to an A record. To customize priorities, choose
the Custom option and a priority selection table will be shown at the bottom.
Included IP
Address(es)
This setting specifies lists of WAN-specific Internet IP addresses that are candidates to be
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.
18.3.10 PTR Records
PTR records are created along with A records pointing to custom IPs. Please refer to
Section 18.3.9 for details. 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.
18.3.11 TXT Records
This table shows the TXT record of the domain name.
