"SoftLayer_" prefix removed for readability.
SoftLayer_Dns_Domain_ResourceRecord_PtrType is a SoftLayer_Dns_Domain_ResourceRecord object whose ‘’type’’ property is set to “ptr” and defines a reverse DNS PTR record on the SoftLayer name servers.
The format for a reverse DNS PTR record varies based on whether it is for an IPv4 or IPv6 address.
For an IPv4 address the ‘‘host’’ property for every PTR record is the last octet of the IP address that the PTR record belongs to, while the ‘‘data’’ property is the canonical name of the host that the reverse lookup resolves to. Every PTR record belongs to a domain on the SoftLayer name servers named by the first three octets of an IP address in reverse order followed by “.in-addr.arpa”.
For instance, if the reverse DNS record for 10.0.0.1 is “host.example.org” then it’s corresponding SoftLayer_Dns_Domain_ResourceRecord_PtrType host is “1”, while it’s data property equals “host.example.org”. The full name of the reverse record for host.example.org including the domain name is “1.0.0.10.in-addr.arpa”.
For an IPv6 address the ‘‘host’’ property for every PTR record is the last four octets of the IP address that the PTR record belongs to. The last four octets need to be in reversed order and each digit separated by a period. The ‘‘data’’ property is the canonical name of the host that the reverse lookup resolves to. Every PTR record belongs to a domain on the SoftLayer name servers named by the first four octets of an IP address in reverse order, split up by digit with a period, and followed by “.ip6.arpa”.
For instance, if the reverse DNS record for fe80:0000:0000:0000:0000:0000:0a00:0001 is “host.example.org” then it’s corresponding SoftLayer_Dns_Domain_ResourceRecord_PtrType host is “1.0.0.0.0.0.a.0.0.0.0.0.0.0.0.0”, while it’s data property equals “host.example.org”. The full name of the reverse record for host.example.org including the domain name is “1.0.0.0.0.0.a.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.e.f.ip6.arpa”.
PTR record host names may not be changed by SoftLayer_Dns_Domain_ResourceRecord::editObject or SoftLayer_Dns_Domain_ResourceRecord::editObjects.
The value of a domain’s resource record. This can be an IP address or a hostname. Fully qualified host and domain name data must end with the “.” character.
Type:
string
The amount of time in seconds that a secondary name server (or servers) will hold a zone before it is no longer considered authoritative.
Type:
int
Whether the address associated with a PTR record is the gateway address of a subnet.
Type:
boolean
The amount of time in seconds that a domain’s resource records are valid. This is also known as a minimum TTL, and can be overridden by an individual resource record’s TTL.
Type:
int
Useful in cases where a domain has more than one mail exchanger, the priority property is the priority of the MTA that delivers mail for a domain. A lower number denotes a higher priority, and mail will attempt to deliver through that MTA before moving to lower priority mail servers. Priority is defaulted to 10 upon resource record creation.
Type:
int
The amount of time in seconds that a secondary name server should wait to check for a new copy of a DNS zone from the domain’s primary name server. If a zone file has changed then the secondary DNS server will update it’s copy of the zone to match the primary DNS server’s zone.
Type:
int
The email address of the person responsible for a domain, with the “@” replaced with a “.”. For instance, if root@example.org is responsible for example.org, then example.org’s SOA responsibility is “root.example.org.”.
Type:
string
The amount of time in seconds that a domain’s primary name server (or servers) should wait if an attempt to refresh by a secondary name server failed before attempting to refresh a domain’s zone with that secondary name server again.
Type:
int
The Time To Live value of a resource record, measured in seconds. TTL is used by a name server to determine how long to cache a resource record. An SOA record’s TTL value defines the domain’s overall TTL.
Type:
int
A domain resource record’s type. A value of “a” denotes an A (address) record, “aaaa” denotes an AAAA (IPv6 address) record, “cname” denotes a CNAME (canonical name) record, “mx” denotes an MX (mail exchanger) record, “ns” denotes an NS (nameserver) record, “ptr” denotes a PTR (pointer/reverse) record, “soa” denotes the SOA (start of authority) record, “spf” denotes a SPF (sender policy framework) record, and “txt” denotes a TXT (text) record. A domain record’s type also denotes which class in the SoftLayer API is a best match for extending a resource record.
