Summary

Detail that the [ and ] characters may enclose a literal IPv6 address populating url.domain.

Background

The current url.domain field description doesn't have guidance for this case (e.g. elastic/elasticsearch#65150 (comment)). The format is defined in RFC 2732 and has been adopted by the major web browsers.

Example:

  • Literal IPv6 address: FEDC:BA98:7654:3210:FEDC:BA98:7654:3210
  • Formatted in a URL: http://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]/index.html

Why are we populating a domain field with an IP address? If we are basing things on RFCs we should have a url.host field (name or ip) and a url.domain fields aligned with the DNS implementation shouldn't we?

I'd think the representation of the url would be dependent on what is reported (which should be []'d for ipv6 I would like to thitnk, but if the browser is not using that rfc I wouldn't want to change it...)

@dainperkins adding another field would be out of scope for this adjustment to the description.

The new guidance around IPv6 addresses remains in line with the previous guidance of populating this field with an IP in .domain, when the URL as an IP for the host. I agree this is not perfect.

But I get the sense that adding another field here leads us to the redesign of normalizing DNS names a bit more across ECS we've been talking about. It's a good idea to look at that, but I suspect it will be a big change that requires an RFC.

* [1.x] Move _meta section back inside mappings, in legacy templates. (elastic#1186) (elastic#1187)

Backports the following commits to 1.x:

* Move _meta section back inside mappings, in legacy templates. (elastic#1186) 

This fixes an issue introduced by elastic#1156, discovered in elastic#1180. Composable templates support `_meta` at the template's root, but legacy templates don't. So we're just putting it back inside the mappings for legacy templates.

This also fixes missing updates to the component template, after the introduction of wildcard in elastic#1098.
