pub const URL_DOMAIN: &str = "url.domain";Expand description
Domain of the url, such as “www.elastic.co”.
In some cases a URL may refer to an IP and/or port directly, without a domain name. In this case, the IP address would go to the domain field.
If the URL contains a literal IPv6 address enclosed by [ and ] (IETF RFC 2732), the [ and ] characters should also be captured in the domain field.
§Examples
www.elastic.co
