I have a program in C# that I want to get a news feed

  • 0

I have a program in C# that I want to get a news feed from a server I setup in my basement. I also want to setup this program so it can work locally. To do this I THINK I need to compare the resolved ip of my dyndns.biz hostname to my router’s public ip (I have dynamic ip and a client on my server updating the ip of the hostname) and thus determine if the hostname needs to be used or the local ip of the server (192.168.0.100) or the hostname. I already have code to connect to the ftp server assuming I can get the right usage of the hostname versus the localized IP.

Edit: Anyways, in summary because I realized this might not look like a question, how can I determine a) the resolved IP of the hostname and b) the public IP of my router in a C# app

    You’re overcomplicating this.
    Just open your hosts file (found in C:\Windows\System32\drivers\etc) and add your dyndns hostname routing it to loopback. That way you don’t have to add any workaround code to your final application to prevent it from even asking your DNS or router:

    127.0.0.1 yourhostname.dyndns.biz
