c++ - Any ip and local ip binding? -


i'm working on network platform creates basic i/o interface make fast/easy. need understand this, main differences between binding ip or local ip socket? why need bind local ip, why need bind ip? simple important question :)

binding server socket local ip instead of 0.0.0.0 can act poor man's firewall if want have server not open entire world, specific group.

for example: - can bind socket local ip if want used way different processes in same machine communicate. - can bind socket ip if want access occur through external load balancer.
