>> Table: ipDnsStaticTable - (.1.3.6.1.4.1.272.4.5.20.18.1)
Description: Contains administrative (static) DNS-entries. Four different entry-types are allowed. 1) 'Positive' entries store names and addresses for building related A/AAAA/PTR-resource-records. 2) 'Negative' (and 'ignore') entries store 'invalid' names for rejecting (or ignoring) related queries/questions. 3) 'Wildcard' entries store 'name-patterns' instead of names. There are two different sub-types. 3a) 'Wildcard-domain-forwarding' entries store nameserver- interfaces/addresses for forwarding related queries. 3b) 'Wildcard-non-forwarding' entries store addresses for building related A/AAAA/PTR-resource-records. They are similar to entries of type 1 but are matching not with a single name but with any name of specified pattern.

Index
Unique index for unambiguous SNMP-addressing, automatically updated to next free/unused value if initialised to 0.
Name
For 'wildcard' entries, specifies name-pattern with leading '*.' substring. (Any further '*' characters in pattern have NO special meaning.) Entry matches if no other (more specific) cache-entries match and if query/question-name is equal to or sub-domain of specified name-pattern. For all other entries, specifies related DNS-name. If contains dots then is treated as full domain-names. Otherwise is treated as simple name to be extended by globally configured domain-name from admin-table. For any entries (wildcard or not), name is automatically copied to 'FullName' field and completed there (i.e. top-domain added for simple names, missing trailing dots added for any names). Length: 0 to 255
IpaddrType
IP-version (ipv4 or ipv6) for ipDnsStaticEntIpaddr. Relevant only for 'positive' entries, excluding such for wildcard-domain-forwarding. Remark: Values 'unknown', 'ipv4z', 'ipv6z', 'dns' are inherited from InetAddressType but are NOT allowed here. Enumerations: unknown (0) ipv4 (1) ipv6 (2) ipv4z (3) ipv6z (4) dns (16)
Ipaddr
IPv4/IPv6-address to be used for name/address-resolution. Relevant only for 'positive' entries, excluding such for wildcard-domain-forwarding. Length: 0 to 255
Response
Field serves multiple purposes. 'delete' means that entry shall be removed. Any other value specifies entry-type. 'ignore'/'negative' means that queries for specified name shall be ignored/rejected. 'positive' means that entry is either 'normal' cache-entry or wildcard (if name starts with '*.'). Normal entries store name and address for building related A/AAAA/PTR-resource-records, and wildcards are used for either doing the same thing for any name of specified pattern or for forwarding queries for certain domains and their sub-domains to other nameservers. Enumerations: ignore (1) negative (2) positive (3) delete (4)
IfIndex
Relevant only for wildcard-domain-forwarding entries with DHCP/IPCP-assigned nameservers (i.e. address not known at configuration-time). Should be set to -1 (unspecified) otherwise. Tells interface-index of nameserver-entry for forwarding matching queries/questions. If wildcard-domain-forwarding-entry does NOT specify nameservers (neither by address nor by interface) then matching queries are forwarded to ANY nameservers from global table.
NameServerAddrType
IP-version (ipv4 or ipv6) for ipDnsStaticEntNameServerAddr. Relevant only for wildcard-domain-forwarding entries with statically configured nameservers. Remark: Values 'unknown', 'ipv4z', 'ipv6z', 'dns' are inherited from InetAddressType but are NOT allowed here. Enumerations: unknown (0) ipv4 (1) ipv6 (2) ipv4z (3) ipv6z (4) dns (16)
NameServerAddr
Relevant only for wildcard-domain-forwarding-entries with statically configured nameservers. Should be set to 0 (unspecified) otherwise. Tells IPv4/IPv6-address of primary nameserver for forwarding matching queries. If wildcard-domain-forwarding-entry does NOT specify nameservers (neither by address nor by interface) then matching queries are forwarded to ANY nameservers from global table. Length: 0 to 255
NameServ2AddrType
IP-version (ipv4 or ipv6) for ipDnsStaticEntNameServ2Addr. Relevant only for wildcard-domain-forwarding-entries with statically configured nameservers. Remark: Values 'unknown', 'ipv4z', 'ipv6z', 'dns' are inherited from InetAddressType but are NOT allowed here. Enumerations: unknown (0) ipv4 (1) ipv6 (2) ipv4z (3) ipv6z (4) dns (16)
NameServ2Addr
Relevant only for wildcard-domain-forwarding-entries with statically configured nameservers. Should be set to 0 (unspecified) otherwise. Tells IPv4/IPv6-address of secondary nameserver for forwarding matching queries. Length: 0 to 255
FullName
Automatically generated: Full DNS-name or name-pattern, derived from administrative 'Name' field. Length: 0 to 255
Hash
Automatically generated: Hash-value of name-field. Relevant only for non-wildcard-entries.
SourceIfIndex
If set it determines the source interface index from which the question was received. In this case it's an additional but optional selector. If this selector doesn't match this entry will not be taken into the account.
NameServerPort
UDP destination port to be used for name/address-resolution in conjunction with ipDnsStaticEntNameServerAddr. The default value is set to '53' - the standard UDP destination port for DNS. This port number will also be used as fallback if ipDnsStaticEntNameServerPort is set to '0'. Range: 0 to 65535
NameServ2Port
UDP destination port to be used for name/address-resolution in conjunction with ipDnsStaticEntNameServ2Addr. The default value is set to '53' - the standard UDP destination port for DNS. This port number will also be used as fallback if ipDnsStaticEntNameServ2Port is set to '0'. Range: 0 to 65535
