"cl" : ResourceClass Resource class. Typically C_IN.
"ttl" : int Time to live for the entry in seconds.
"len" : int Length in bytes of the encoded data section.
Depending on the type of entry the mapping may contain different additional fields:
T_CNAME "cname" : string
T_PTR "ptr" : string
T_NS "ns" : string
T_MX "preference" : int "mx" : string
T_HINFO "cpu" : string "os" : string
T_SRV RFC 2052 and RFC 2782.
"priority" : int "weight" : int "port" : int "target" : string "service" : string "proto" : string "name" : string
T_A "a" : string IPv4-address in dotted-decimal format.
T_AAAA "aaaa" : string IPv6-address in colon-separated hexadecimal format.
T_LOC "version" : int Version, currently only version
0
(zero) is supported."size" : int "h_perc" : int "v_perc" : int "lat" : int "long" : int "alt" : int
T_SOA "mname" : string "rname" : string "serial" : int "refresh" : int "retry" : int "expire" : int "minimum" : int Note: For historical reasons this entry is named
"minimum"
, but it contains the TTL for negative answers (RFC 2308).
T_NAPTR "order" : int "preference" : int "flags" : string "service" : string "regexp" : string "replacement" : string
T_TXT "txt" : string Note: For historical reasons, when receiving decoded DNS entries from a client, this will be the first string in the TXT record only.
"txta" : string When receiving decoded DNS data from a client, txta is the array of all strings in the record. When sending multiple strings in a TXT record in a server, please supply an array as "txt" containing the strings, txta will be ignored.
T_SPF "spf" : string
