Which of the following devices is most likely to be assigned a public IP address?

A router that connects your home network to the internet.

You need to design a network that supports 275 hosts. You want to place all hosts in a single broadcast domain, and you want to make sure you do not waste IP addresses. How should you implement your plan? Connect a router to a switch with a single connection. Create two subinterfaces on the router. Use a mask of 255.255.255.0 for each subinterface. Use a router to create two subnets, with half of the hosts on each subnet. Use a mask of 255.255.255.0 on each subnet. Use a router to create two subnets. Put 250 hosts on one subnet and 25 hosts on the other subnet. Use 255.255.255.0 and 255.255.255.224 as subnet masks. Place all hosts on the same subnet. Use a mask of 255.255.254.0. Use a bridge on a single subnet. Use a mask of 255.255.255.128 for each bridge port.

Place all hosts on the same subnet. Use a mask of 255.255.254.0.
