does not belong to. A network card can also assign multiple IP,. Each IP has its own port correspondence. For example, you have an ip: 192.168.1.1
.but at the same time you must have a loopback ip 127.0.0.1. If a program listens on port 1234 of 127.0.0.1, then port 192.168.1.1 1234 is still not occupied.

using 4 terminal windows and using nc to monitor the same ports of two ip (192.168.1.13 and 127.0.0.1) of this machine, you can establish different links at the same time without interfering with each other.
