Verified-TCP/IP Concepts

A host with IP address 192.168.1.50/24 needs to communicate with 192.168.2.100. What will the host do?

• Send packet directly using ARP

• Forward packet to default gateway

• Broadcast to all network hosts

• Drop packet as invalid destination

What is the purpose of a subnet mask in IPv4 addressing?

• Encrypt network communications

• Distinguish network ID from host ID

• Assign MAC addresses to devices

• Control wireless access

Which IPv4 address ranges are reserved for private use? (Choose all that apply)

• 10.0.0.0 to 10.255.255.255

• 172.16.0.0 to 172.31.255.255

• 192.168.0.0 to 192.168.255.255

• 169.254.0.0 to 169.254.255.255

A Windows computer shows IP address 169.254.100.50. What does this indicate?

• DHCP server assigned this address

• Static IP configuration is active

• APIPA activated due to DHCP failure

• Router provided this address via NAT

In IPv6 addressing, what portion of the 128-bit address is used for the network ID?

• First 32 bits

• First 48 bits

• First 64 bits

• First 96 bits

True or False: IPv6 hosts need to be manually configured with a default gateway address.

• True

• False
