Question 1

• the primary protocol for everything that we do

• example: 192.168.1.131

Answer 1

IPv4 Addresses

Question 2

• now part of all major operating systems

Answer 2

IPv6 Addresses

Question 3

• unique IP address
• subnet mask
• default gateway

Answer 3

• for example, 255.255.255.0

Answer 4

Subnet Mask

Question 5

• the IP address of a router that allows you to communicate outside of your local subnet
• must be an IP address on the local subnet
