SVCB adds an SVCB record to a domain. The name should be the relative label for the record. Use `@` for the domain apex.
|
|
|
|
The priority must be a positive number, the address should be an ip address, either a string, or a numeric value obtained via [IP](../top-level-functions/IP.md).
|
|
|
|
The params may be configured to specify the `alpn`, `ipv4hint`, `ipv6hint`, `ech` or `port` setting. Several params may be joined by a space. Not existing params may be specified as an empty string `""`
|
|
|
|
Modifiers can be any number of [record modifiers](https://docs.dnscontrol.org/language-reference/record-modifiers) or JSON objects, which will be merged into the record's metadata.
