different name and different IP on a single m/c

Question

I am just a beginner in ip domain etc..I had two questions: if I have configuration on "same" Machine(win or lin) in host file like:

m/c name : IP(Example)

mac1.net.com 10.124.77.10 and mac2.net.com 10.124.77.11

We can say "different name and different IP on a single m/c". Will some application fail or will i get ipconflict if i/some application tries to access this m/c .

Secondly,If i have "IP:port-combination" 10.124.77.10:5650 occupied by some process XYZ ,will another process ABC be able to use 10.124.77.11:5650

I don't know what m/c stands for, but having a machine with multiple addresses assigned to it is not uncommon.

Secondly,If i have "IP:port-combination" 10.124.77.10:5650 occupied by some process XYZ ,will another process ABC be able to use 10.124.77.11:5650

If your processes are bound to those specific interfaces, then yes. Processes can also bind to a wildcard of a given port on all interfaces, though. It depends on your configuration.

m/c = machine ,sorry for confusion – shashank May 22 '12 at 14:26
ok... so by above discussion we can have: process1 running on 10.124.77.10:5056 ..... and process2 running on 10.124.77.11:5060..... (means, different name and different IP on a single computer/machine ) – shashank May 22 '12 at 14:31
@shashank Yes, that is correct. – Jeff Ferland May 22 '12 at 14:42

No, this is a common scenario.

This depends on your scenario. Usually, you are not able to use the same port twice to listen on with different applications. In Windows 7/2008 R2 there is a concept called Port Sharing (http://technet.microsoft.com/en-us/library/cc772001.aspx) which allows for several Communication Foundation applications to share a port. The same holds true for web servers, where different "web applications" can share a common port (usually http/80 or https/443)
