Hi! Yes, with dynamic IP addresses, your IP can change periodically, especially with certain internet service providers like Converge. The frequency of IP address changes can vary, but it typically happens whenever your modem/router reconnects to the internet. This can occur when you restart your device, when there's a network interruption, or at regular intervals set by your ISP.
In your case, if you need a static IP to consistently access your work server, you might want to consider requesting a static IP address from your ISP. This will ensure that your IP address remains the same, making it easier for you to access your work server without needing to constantly update the IP with your admin.
If a static IP is not feasible, you may need to find a way to automate the process of updating the IP address with your admin whenever it changes. This could involve setting up a script or using a dynamic DNS service to keep track of your changing IP address and provide a consistent domain name for accessing your server.
I hope this helps clarify why your IP address changes and provides some potential solutions for your situation! Let me know if you have any more questions.
