Does a switch have an IP address? When computers are on the same IP segment, it means that the computers belong to the same network. But since the switch does not have the capability to assign IP addresses, the computers connected to it will not be able to communicate with each other. They will get an Automatic Private IP Address (APIPA).
What is router vs switch? Router and Switch are both network connecting devices. Router works at network layer and is responsibe to find the shortest path for a packet whereas Switch connects various devices in a network. Router connects devices across multiple networks.
Can a switch work without a router? So while you can use a switch to create a LAN that networks local devices without a router, the devices all have to be connected by physical Ethernet cables. In addition, you wouldn’t be able to effectively share an internet connection between all of the devices without connecting the switch to a router.
Who provides IP address? IP addresses are not random. They are mathematically produced and allocated by the Internet Assigned Numbers Authority (IANA), a division of the Internet Corporation for Assigned Names and Numbers (ICANN).
