DESCRIPTION
Double-click an entry or select it and click Edit to be able to modify the
entry's settings.
To remove an entry, select it and click Remove. The NXC confirms you
want to remove it before doing so. Note that subsequent entries move
up by one when you take this action.
This is the index number of the address/PTR record.
This is a host's fully qualified domain name.
This is the IP address of a host.
This specifies a DNS server's IP address. The NXC can query the DNS
server to resolve domain zones for features like the time server.
When the NXC needs to resolve a domain zone, it checks it against the
domain zone forwarder entries in the order that they appear in this list.
Click this to create a new entry. Select an entry and click Add to create

This is the index number of the domain zone forwarder record. The
ordering of your rules is important as rules are applied in sequence.
A hyphen (-) displays for the default domain zone forwarder record.
The default record is not configurable. The NXC uses this default record
if the domain zone that needs to be resolved does not match any of the
other domain zone forwarder records.
A domain zone is a fully qualified domain name without the host. For
example, zyxel.com.tw is the domain zone for the www.zyxel.com.tw
fully qualified domain name.
A "*" means all domain zones.
This displays whether the DNS server IP address is assigned by the ISP
dynamically through a specified interface or configured manually
(User-Defined).
This is the IP address of a DNS server. This field displays N/A if you
have the NXC get a DNS server IP address from the ISP dynamically
but the specified interface is not active.
This is the interface through which the NXC sends DNS queries to the
entry's DNS server.
A MX (Mail eXchange) record identifies a mail server that handles the
mail for a particular domain.
