Why would 11,100 be recognized as a valid value to begin with?

Vs, why was this remote facing, and why don't they have a definitive answer on if it's an USA or non USA ip address.

Sounds like no logs, probably showed up on shodan and someone wanted to have fun/many people did.

The geolocation of the IP isn't all that useful, it could be a VPN or an owned machine.

Disagree, if it was USA, it is easily possible to enforce a warrant and maybe you're lucky it's residential.

If it was an VPN, you know it's a more competent person, org, and most VPN's also, keep logs.

parent mentioned "owned machine" (as in, "hacked" not "ownership"), which means you might be able to find the source if you can seize the computer and analyze it in time. If the attacker wiped all traces from the computer then at best the trail ends there and at worst an innocent person gets blamed for it.

"no log" is a commonly sought after feature in VPNs, and if you're planning to do shady stuff I doubt you'll go with a logged vpn.

It's marketing puffery, they all log and they all keep it and will comply. Many VPN say no log, and then logs leak. You don't have control over that system/service, you can not fully verify and there is much mistrust around it for nefarious deeds.

So, yes, and no. The IP address will determine location and possible people of interest. It could also lead to a chain or more documentation/possible past interest/threat.

The wiping/forensics imo are hard to ensure for chain of custody, but if an IP address is honed to residental, it's easy to grab a DNS log from that ISP and see what requests they amde and if it makes sense it was targeted, random shodan or possible hijacked/RAT machine.

More info never hurts, but "tracing" an IP address is the first step.

Even if it is residential IP, it could be a residential proxy. A proxy from end-user machine that allows anonymous user to connect through its ISP for online activities.

Maybe to have a Cleaning Cycle once a year? But yeah there is a lack of security there.
