Simple Socket Chat

So, i've recently been using a Socket chat for communication between my applications and a small server i run off my old desktop so i can update my applications and broadcast MOTD's, etc. However, i've noticed that my method isn't at all reliable nor time efficient as it is kind of slow. I will post a snippet of the socket chat later on. But for now, i was wondering whether there is a more efficient or reliable method.

Also, seeing as my IP for the desktop sometimes does change would there be a more reliable method for this (Someone suggested DNS or a VPS but no thx. broke atm.)?

Edit: By server i mean an application i made to respond to the client's requests and send out data under my control.

I'd go with dns. A free one like "noip dotcom" ...they have a client-side program that runs on your desktop pc and connects to their dns server so keep your ip up to date. Worked well for me before. There aren't a whole lot of other options that I can think of.

Looking forward to post. All the examples I've seen are either synchronous or 1-thread-per-client which doesn't scale well. If you don't expect a lot of connections, I might be able to help out. I posted something similar a week ago, but didn't get much response, hopefully you do.
