ZDNS supports the following DNS record types: A, AAAA, CNAME, MX, TXT, PTR, SRV.
Record Type Descriptions
A Record
Maps a domain name to an IPv4 address; supports wildcard entries.
Domain prefix
IPv4 address in dotted-decimal format (e.g., 192.168.1.2). Multiple entries supported with optional weights.
AAAA Record
Maps a domain name to an IPv6 address; supports wildcard entries.
Domain prefix
IPv6 address (e.g., ff03:0:0:0:0:0:0:c1). Multiple entries supported with optional weights.
CNAME Record
Maps a domain name to another domain name, inheriting its resolution result.
Domain prefix
Domain format (e.g., abc.example.com).
MX Record
Specifies the mail server responsible for receiving emails.
Domain prefix
Domain format (e.g., abc.example.com).
TXT Record
Stores arbitrary text, commonly used for verification (e.g., SPF anti-spam checks).
Domain prefix
String format; allowed characters include letters, digits, and *?-_~=:;.@+^/!”.
SRV Record
Defines service records specifying which server provides a service.
Typically _<service>._<protocol> (e.g., _sip._tcp)
Format: [priority] [weight] [port] [target], each 0–65535, separated by spaces. Example: 0 5 5060 sipserver.example.com.
PTR Record
Enables reverse DNS lookup (IP → domain name).
For IPv4, typically a number from 0–255
Domain format (e.g., abc.example.com). Example: For 192.168.0.1/24, the zone name is 0.168.192.in-addr.arpa, with record 5 -> abc.example.com, meaning a query for 192.168.0.5 returns that domain.
