The default DHCP configuration on a home wireless router assigns which type of addresses to devices?

• A. Private IP Addresses
• B. Public IP Addresses
• C. Reserved IP Addresses
• D. Shared IP Addresses

Answer: (A)

DHCP is used to automatically assign addresses and basic network settings to devices so they can communicate on the local network. In a typical home network, the DHCP server in the router hands out addresses from private IP ranges defined for internal use (such as 192.168.x.x). These private addresses are not routable on the public Internet, which is why the router uses network address translation (NAT) to map those private addresses to the single public IP it obtains from the ISP for outbound traffic. So, devices on the home LAN receive private IP addresses by default. Public IPs would expose every device on the Internet, which isn’t how home networks are set up. Reserved addresses can be used in some cases (via static reservations), but that isn’t the default behavior, and shared IP addressing isn’t how DHCP assigns addresses.
