Hello all. I recently switched internet providers and I am trying to self host a minecraft server, which I have done many times before succesfully. I have not tried since switching ISP's. I just tried, and my friend is unable to join. My IP address says I am in Denver, while I live a state away. I remember briefly hearing a term for this, where ISP's put public IP's behind one, or something like that I don't really know. But, does anybody know what this is and how to get around it?

Edit: thank you all for such quick responses and for your knowledgable responses, i'm looking into requesting a designated IP from my ISP, if that doesn't work then it looks like i've got a new concept to learn.
