Where on my system are these dead entries stored? to monitor the API calls, but I still cannot figure out where this information is coming from. but the entries are nowhere to be found.įurthermore, I've even tried using Process Monitor, API Monitor, etc. I've searched the registry, the files in my \Windows folder, the application's files, etc. The fact that this information persists across reboots and network disconnections implies it has to be stored somewhere on my computer itself.įor the life of me, I cannot figure out where these entries are stored. not in ipconfig /displaydns, not in arp -a, not anywhere else. I don't see this information anywhere else. This wouldn't be so weird if it weren't for the fact that I still see these even if I disable my network card, clear my DNS cache, and reboot while still disconnected from any network.
Specifically, I can see the devices' last-known host names, NetBIOS names, IP addresses, MAC addresses, and even manufacturers. NOTE: If the difference between the start and the end port is more than 500 then in that case the scanning can take longer to finish and in some cases where the difference is far too high, the scanning might never complete, so it's recommended to keep the port range short.Advanced IP Scanner has the ability to show "dead" entries-devices that were at some point visible on the network, but which are no longer reachable.
The recommended scan type is "connect()", however other scan types can also be useful depending on the network of the target host, a "SYN Stealth" scan type can also prove to be useful when there's a firewall blocking the ports.
To scan a host just enter the host name or the IP address in the box above and give a range of ports to scan, if the host has firewall enabled then you can try a different type of scan in the advance mode. The service can also detect uptime of a host if the host is running one of the known Operating Systems which the scanner can analyze to guess uptime. Port scanner tool can be used to identify available services running on a server, it uses raw IP packets to find out what ports are open on a server or what Operating System is running or to check if a server has firewall enabled etc.
