I am trying to run and connect multiple nodes on a single machine, i.e different nodes using different ports. I am having trouble in connecting the nodes and making them talk to each other. While debugging, I inserted a LogPrintf("%s\n",addr) in the while loop of ThreadOpenConnections() in net.cpp file.
The output in the debug.log file is always [::]:0. What does this address mean ? Is it for localhost representation or something else ?
[::] is IPv6's version of localhost (0.0.0.0).
[::] or [::0] is 'unspecified', equivalent to v4 INADDR_ANY = 0.0.0.0; [::1] is the equivalent of INADDR_LOOPBACK = 127.0.0.1. See en.wikipedia.org/wiki/IPv6_address#Special_addresses

[::]:0 must then mean 0.0.0.0, port 0.
