The name of the application. The attribute name and value of is used in the applications RDN.

DnsMaxNumberCachedRecordsDT |
-
dnsCacheSize
=
20000
-
This attribute defines the maximum number of cached resource records.
|
DnsExpiredCacheBehaviorDT |
-
dnsExpiredCacheBehavior
=
REMOVED
-
This attribute defines the life cycle management of cached resource records.
|
DnsLocalAddressDT[0..10] nonUnique ordered |
-
dnsLocalAddress
=
0.0.0.0
-
The IP address of the local host. Used as source IP address in DNS queries.
Note1: If no attributes have been specified the system will select a local address.
Note2: To make the system less vulnerable to cache poisoning it is recommended that multiple entries are specified.

DnsRetransmissionTimerDT |
-
dnsRetransmissionTimer
=
10
-
This attribute defines the retransmission timer for the DNS stack, to retransmit queries to the external DNS server.

DnsServerEntryDT[0..] nonUnique ordered |
-
dnsServerEntry
=
0:0.0.0.0
-
This attribute defines the following properties of a DNS server:
- lookup
- priority
- address
- port
address is mandatory. The address is either an IPv4 address or an IPv6 address enclosed in square brackets. It is possible to configure several attributes. There may be a mix of IPv4 and IPv6 attributes.
port is optional. No colon (':') separator shall be used if port is left out. If not configured, port is assigned a default value of 53 by the system.
Example: 10.1.1.1
[::6]:53
lookup is optional. No colon (':') separator shall be used if lookup is left out. When a DNS Server is configured with a specific lookup, the DNS Server is dedicated to handle DNS queries for that lookup. If lookup is not specified, the server is considered as a general server handling all sorts of DNS queries for which no specific DNS server is applicable. Several lookups can be specified for a given server.
Example: 10.1.1.1
[::6]:53
http:[2000::4:1]
tel:[2000::4:1]
priority is optional. No colon (':') separator shall be used if priority is left out. The priority controls which distribution mechanism to be used. Two distribution mechanisms are supported: Primary/Standby and Load Sharing. If a Primary/Standby distribution mechanism is required, the Primary Server shall be assigned the lowest priority value; the first Standby server shall be assigned the second lowest priority value; the second Standby server shall be assigned the third lowest priority value; etc. The Primary/Standby distribution mechanism is relevant to DNS servers of the same lookup (or no lookup). If a Load Sharing distribution mechanism is required, the same priority value shall be assigned to these DNS Servers. These servers form a load sharing group. The load sharing distribution mechanism is relevant to DNS servers of the same lookup (or no lookup). In case priority is not specified, Primary/Standby distribution mechanism will apply, and the system will assign a priority (next available value) for that lookup.
Example: 0:10.1.1.1
1:[::6]:53
http:0:[2000::4:1]
tel:0:[2000::4:1]
Within each lookup both distribution mechanisms can be applied as it is possible to specify several load sharing groups for a certain lookup. Then the servers with the same lowest priority constitute a Primary group, the servers with the same second lowest priority constitute a Standby group, etc.
Example: 0:10.1.1.1
0:10.1.1.2
0:10.1.1.3
1:[::6]:53
1:[::7]
http:0:[2000::4:1]
http:0:[2000::4:2]
http:1:[2000::4:3]
http:1:[2000::4:4]
http:2:[2000::4:5]
http:2:[2000::4:6]
tel:0:[2000::4:1]
tel:0:[2000::4:2]
tel:0:[2000::4:3]
tel:1:[2000::4:4]
tel:1:[2000::4:5]
Note: Attribute DnsServerEntry is used together with attribute DnsLocalAddress. This means that some entries of DnsServerEntry may be ruled out. A DnsServerEntry entry is ruled out if the IP version does not match the IP version of any DnsLocalAddress entry. For example if multiple DnsServerEntry entries have been specified with a mix of IPv4/IPv6 entries while attribute DnsLocalAddress only consists of IPv4 addresses, then none of the IPv6 entries for DnsServerEntry will be used.
