🔖 Feature description

Record the resolved IP address of the instance targeted for the health check.

✔️ Solution

Ideally we would like Uptime Kuma to record the resolved DNS entry at the time of the request. This would be something like the results of dig www.example.com A performed immediately preceding the HTTP(S) health check. Alternatively this could use the IP of the instance responding to the health check.

This check would ensure that DNS is not pointing to a stale/invalid record as a cause of the failed check.

❓ Alternatives

We use a separate service for DNS propagation checks, as well as querying name servers using dig.

I think this is a duplicate of #432
If you agree, could you please close this Issue, as duplicates only create immortal zombies and are really hard to issue-manage?
If not, what makes this issue unique enough to require an additional issue? (Could this be integrated into the issue linked above?) ^^

I read this request as a different request. In my opinion it's worded a bit strangely, but what I think it's about is logging the actual IP address that was connected to.

For our use case: we have a monitor that sometimes complains about a wrong certificate. This certificate is for a completely different server (that is being monitored). If the monitoring message would show what IP address was connected to in order to retrieve the bad certificate, that would help us locate the problem.
