I use a relatively low-cost host for my personal server, and occasionally I get a rash of downtime alerts. These are all from today.
If my host were to ("accidentally") assign my IP to someone else, and that server came online and started fighting with mine for control of the IP, would it look like this? If not, I guess I have to assume the host is having hardware or network issues, or is possibly dealing with some sort of DoS attack, right? Of course, their client portal and company website are also suffering downtime, too; making it all but impossible to contact them and ask what's happening.
In the past I have occasionally seen this type of activity correlate with attempting to access my website and seeing the default website from a different server (which makes sense, since they wouldn't have host settings for my domain).
Short of manually checking all of my domains to see if something unexpected comes back, is there anything I can do to detect someone else attempting to use my IP address?
