dns response

[Simon-CR]

So for some reason, I often receive the dns response with only v6 and not v4. Making it impossible to use and failing to browse/access the target website.

for example:

using gravity:

nslookup dl-cdn.alpinelinux.org

Non-authoritative answer:
dl-cdn.alpinelinux.org	canonical name = dualstack.j.sni.global.fastly.net.
Name:	dualstack.j.sni.global.fastly.net

What was the zone configuration when this happened?
