Good Day Experts.
I have what is no doubt a rudimentary networking question that I need to be 100% clear on.
We have several class c ip ranges with our ISP (Let's call them Q). They were assigned to us when we got our first T1 almost 15 years ago. Since them we have added multiple T1 circuits from Q.
We need to move to a fiber circuit that will do away with the multiple T1 circuits. We want keep Q as our isp however we are being told that we will almost certainly not keep our ip assignment.
So my question is why not? I've asked them and haven't been able to comprehend their reasoning so I am hoping you can clear this up for a very lay man.
If we are staying with the same ISP why can't we keep our ip's?
