DNS Record Configuration

4.2 DNS Record Configuration

This DNS record is associated with the zone specified by the user. The Record type in the following table are currently supported:

Table 4-3 Resource Record

Type	Description	Function	RDATA format
NAPTR	Naming Authority Pointer	Allows regular-expression-based rewriting of domain names which can then be used as URIs, further domain names to lookups.	Order, preference, flag, Regex and replacement domain.
NS	Name server record	Delegates a DNS zone to use the given authoritative name servers	Domain Name (A record must be present for this domain). If "." is not added to the end of RDATA, origin (zone name) is appended to it. If "." is added, nothing is appended to the RDATA. NS records cannot be looked up, these are only shared in the authority section.
A	Address record	Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host.	IP address
AAAA	IPv6 address record	Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host.	IPv6 address
CNAME	Canonical name record	Alias of one name to another. The DNS lookup continues by retrying the lookup with the new name.	Canonical Domain name If "." is not added to the end of RDATA, origin (zone name) is appended to it. If "." is added, nothing is appended to the RDATA.
SRV	Service locator	Generalized service location record, used for newer protocols instead of creating protocol-specific records.	Priority weight port target
PTR	PTR Resource Record	Pointer to a canonical name. Unlike a CNAME, DNS processing stops and just the name is returned. The most common use is for implementing reverse DNS lookups.	Canonical Name If "." is not added to the end of RDATA, origin (zone name) is appended to it. If "." is added, nothing is appended to the RDATA.

Note:

Before upgrade, it is recommended to delete all the invalid DNS Record entries from GUI for which the DNS alarm is Active. If these are not deleted, then all the DNS Config alarms for invalid DNS entries can be cleared after the upgrade, but GUI shall still hold the invalid entries.
