Recently a new IP Address has appeared on a network monitor I use in addition to my router address of 192.168.1.1 This is 192.168.1.114 which according to Google "isa private IP address and directly related to your Wi-Fi network. It is the chain of numbers you use to access the router admin page. However, as briefly mentioned, your router also has another public IP address."
Taking Gondola's explanation into account, by a process of elimination I have discovered this IP address is in fact for my Iphone, a change from the previous one.
The IP address will have been allocated by the router. So at some point there will have been a network connection. That connection may expire when the lease for that IP address expires if the device does not remain connected.
If IP addresses are allocated dynamically and not reserved for specific devices then, over time, the allocated IP addresses can change.
Yes, it's not a registered MAC address which means it's most likely a randomised MAC address often used for mobile devices that decline to be tracked from one access point to another.
I assume the device is connected to your router by Wi-Fi and not an Ethernet connection.
You can always block the MAC address to see if any of your devices get disconnected. And then see if a new device appears.
Have you captured the MAC address of the device that's been assigned the IP address 192.168.1.114 as there's a possibility of identifying the manufacturer from the first part of the MAC address. Not always possible though.
