Are the modems with the four ports considered routers?
Those are called, "Residential Gateways"; and, yes, they comprise a router and modem combined in one box. Fairly common with DSL service; not so much with cable service.
I have worked with two models. I don't recall which one CenturyLink issued for my mother, other than it was VDSL. My ISP issued an ADSL2+ RG. I found it rather limiting, compared with my old D-Link DIR-655. So I brought the old ADSL2+ modem from another residence, and combined it with an ASUS RT-AC66U.
IMO, a separate modem and router is preferable to an RG. ISPs will always "cheap out" on the CPE.--
