I am using BSD sockets over a wlan. I have noticed that my server computer’s ip address changes occasionally when I connect to it. The problem is that I enter the ip address into my code as a literal string. So whenever it changes I have to go into the code and change it there. How can I change the code so that it will use whatever the ip is at the time? This is the call in the server code

if ((status = getaddrinfo("192.168.2.2", port, &hints, &servinfo)) != 0)

and the client side is the same. I tried NULL for the address on both sides, but the client will not connect and just gives me a “Connection refused” error.

Thanks for any help.

    Use a domain name that can be looked up in your hosts file or in DNS, rather than an IP address.
