My ISP (providing fiber optic service) has told me that they will be able to provide 2 static IP addresses through the single fiber optic line to the house. A standard RJ45 (I believe that's what it is) ethernet cable enters the house that will, presumably, carry both of these IP addresses.
I would like to separate the two IP addresses that are present on this single physical cable into two separate cables, one carrying each IP address.
What piece of equipment do I need to purchase to do this (specifically)? I gather this is a switch or gateway of some sort, but I do not know exactly what identifies this piece of equipment.
