resolve

Resolves the record of a second-level domain with the specific type. The maximum resolving depth is 2.

For example, when you resolve a domain "test.neo" with the IPV4 type:

  • if the domain has a IPV4 record, then the record is returned directly

  • if the domain has a canonical name record "alias.neo", which involves a IPV4 record, then the IPV4 record is returned.


Parameters

NameTypeDescriptionRequired

name

String

The second-level domain, e.g. "test.neo"

Required

type

Integer

Available types are: 1 - IPV4 address record 5 - Canonical name record 16 - Text record 28 - IPV6 address record

Example

Request body #1

In this example, suppose "test1.neo" has no text record, but it has the cname record "test2.neo"; "test2.neo" has no text record, but it has the cname record "test3.neo"; "test3.neo" has a text record "test3". Then resolving "test1.neo" with the text record will return test3.
