For a socket based application : how must I handle dynamic ip adress?
I plan to write an network application whose use steps is the following :
What did network programs use to communicate before sockets was invented (around 1983?)
Sockets were invented in Berkeley around 1983, but how did networked computer programs work before this? These days, pretty much everything uses sockets, so it’s hard for me to imagine how else programs could communicate and Google turned up nothing.

Are there security implications to using dynamically-assigned TCP port numbers?
I’m getting pushback from operations for having a server process listen on a dynamically-assigned port number (i.e. it binds a socket to a port number of 0, triggering a dynamic assignment by the OS, which it retrieves using getsocketname()). The argument was that is “creates all kinds of issues for firewalling, routing, ACL, and security purposes”. I haven’t run across anything about this.

Android Design – Service vs Thread for Networking
I am writing an Android app, finally (yay me) and for this app I need persistant, but user closeable, network sockets (yes, more than one). I decided to try my hand at writing my own version of an IRC Client.
Should I lock a list of objects while a socket is receiving messages?
I have a scenario where I will be receiving messages through a socket connection. I also need to keep a list of 100 messages (such as List) and periodically toss out old messages from the list when a condition is met.
