Can different IP addresses use the same port?
It is possible. You just have to bind on the right IP address/interface each service using the same port. Ports (be them UDP or TCP) have their own pool per IP address. You can listen on the same port if you change: IP address or protocol (UDP or TCP).
Can multiple processes use the same port?
The short answer is “no, not on the same host.” Applications generally do so by having a single task dedicated to accepting incoming connections and, for each accepted connection, allocating resources to service it. …
Can two different IP addresses connect to the same port on a given Web server?
Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

Why do we need both IP address and port address for process communication?
IP address is the address of the layer-3 IP protocol. Port number is the address of the layer-4 protocols. IP address identify a host/computer on a computer network. Port numbers are logical interfaces used by communication protocols.
Is the same port used for two different IP addresses?
Just as two different buildings may have a room 101, the rooms are not the same room. 10.1.2.3:1234 is a different port than 172.16.17.18:1234. The function of the port may be the same across IP addresses or protocols (e.g., IPv6 ports have the same functions as IPv4 ports, even though they are different protocols).
How many applications can use the same IP address?
With two IP addresses, you could have four applications using the same port number (2 addresses, each with the same port number for both UDP and TCP). You seen to think the IP address binds to the port, but it’s the other way around.
Which is an example of using the same IP address for multiple frontends?
