No, a switch is a Layer2 802.3 device to distribute the ethernet signal in your network allowing the user to "daisy-chain" the together or to expand the number of switch ports from your providers gateway (Router) device. A router is a Layer3 store/forward device designed to connect networks together, it acts like a "gateway" between your network and the ISP's network. Most home routers also provide non-routable IP address via DHCP server, Firewall services to hide your IP addresses, and connect your network to the ISP DNS name server. While you can use a switch without a router. to connect all your local devices, without a "gateway" / router your traffic will never leave your network. - Ich bin ein IT nerd
Sorry, there was a problem. Please try again later.A switch may or may not act as a router, and most routers will have multiple ports so they can act as a switch, 1 to 1 connections do not even need a switch between them if cabled correctly. Multiple devices that are assigned static IP addresses can usually see each other if they are on the same IP group and subnet. Think 192.168.0.xxx and 192.168.0.yyy with both having subnet 255.255.255.0 assigned to them. If you are expecting to have IP addresses automatically assigned via DHCP, then you will need a router to do that job for you.
