dns: domain must be fully qualified / or what does it do?

[rrjanbiah]

Getting domain must be fully qualified error with:

{
  "type": "dns",
  "endpoint_name": "Testing DNS",
  "endpoint_url": "1.1.1.1:53", // cloudflare 
  "hostname_fqdn": "foo.com"
}

While Googling the error it seems to suggest that it is trying to update DNS (which I don't want). So, what does it exactly do?

[titpetric]

The fully qualified domain name consists of three or more labels: The top level domain, the domain names, optional subdomains, and the host name.

So, from what I understand, a www.foo.com should be a fqdn, while foo.com is not. You could try with foo.com. (trailing dot), but i'm not sure that it's going to work.

@titpetric Thank you so much for your quick reply. So, is it different from nslookup? IOW, is it to check if the given hostname is resolving? TIA

Also, for the sake of record trailing dot fixed it.

What can we do better?

• don’t require a fqdn (a less strict check),
• assert resolved ips against []string list of IPs,
• check ipv6 options (AAAA record)

If you have other suggestions, please add a comment with a related feature request for the dns checker, or a new issue if a different area of checkup

@titpetric I think, current checks are perfectly fine. Some doc or sample config will suffice, IMHO.
