When we start geth console and run admin.peers it gives the following output(not always) and disappears after sometime . We have not added any peers at the time of occurrence of the issue. Our system is in a private network and the machine is not accessible publicly over the internet. How is the foreign node getting connected to our network, without enode information and also without a public IP to connect to this network?
caps: ["eth/62", "eth/63"],
Geth version: 1.8.12
OS & Version: Windows 2012 server 64 bit
Ideally it should return  when no peers are added.
