I work at an office on which I do accounting and I'm being asked by the owner, since I'm somehow the I.T. guy, to cordinate to switch out our ISP provider. Before we just had a T1 connection which went from a jack in our phone run to a switch, but now since a new provider is coming on board and were getting rid of the old one, I'm supposed to get a router. As I understand this, physical mentally, I was told that we are supposed to go from a model over to a router and then to the present switch we presently have. I was also given about five IP's which I'm not sure why or how to configure them.
Can someone assist in understanding this concept and also mention as to how to go about this?
