    Here is my problem:

    I have a serious problem at work.
    We had a local network that I managed with the internet. So we were using Class C IP addresses on this network.
    Now we have a server that I installed. Now the ISP has given me a Class A IP address so that I can configure the server to be accessible via the internet. When I put this IP where we set the IP addresses, the network doesn't work anymore. How can I configure a web server on this server and where should I put the IP that the ISP provided me? Help please!
    Thank you in advance!

    What is the connection between internet access and class 'C' addresses in a local network?

    Now we have a server that I installed. Now the ISP gave me a class A IP address so that I can configure the server to be accessible via the internet.

    Why did they give an IP address? What was your request to this ISP?

    Before this famous server, you said that you already had internet access: you must have had at least one public IP address with which your LAN could browse.

    Did you make a specific request for this server?


    When I put this IP where we set the IP addresses, the network stops working. How do I configure a web server on this server and where should I put the IP that the ISP provided me?

    Ah... so this server is a web server: it would have been nice to explain that from the start! :)

    Your server should keep its private IP address: it's on the equipment that connects you to your provider that you need to place this new IP: usually, this equipment is a router/modem/ADSL

    The function that allows you to switch from a local address to the one provided by your ISP is called NAT (network address translation)

    What is your ISP? What equipment is used? What is your server connected to? How does it connect to this ISP gateway?

    Generally, a clearly asked question, a clearly explained problem increases the chances of getting a response: there is no need for the eventual reader to spend 3 hours deciphering what was intended and to have to come up with 25,000 hypotheses due to a lack of precision about the environment in which you are located.
