1440228 - about:networking shows incorrect family

Status: NEW

(Core :: Networking: DNS, enhancement, P3)

Description

[--]

When looking at the DNS cache in the about:networking view, the list says "IPv4" even for host names that resolves to both IPv4 *and' IPv6 names (AF_UNSPEC).

Example from my current Firefox nightly (60), clearly showing a host name with mixed addresses and yet saying it is IPv4-

Hostname: tensions.settings.services.mozilla.com
Family:   ipv4
Addresses: 

2620:108:700f::23a3:f9e0
2620:108:700f::36c9:ec30
2620:108:700f::3422:17fb
54.201.236.48
52.34.23.251
35.163.249.224

Expires: 38

I would propose that we just drop the "family" column from the display...

I can confirm (was just about to open a bug myself, when I saw this).

I'm on an IPv6-only system, with a kernel that doesn't even have the IPv4-stack. Still it states 'family IPv4' with every query in about:networking#dns

This is caused by this line
If the request is AF_UNSPEC or AF_INET, then it's "ipv4", regardless of whether the response only includes IPv6 addresses.
