Words to know

IP address
The address of a device on the internet, like a house number for your connection. Websites need it to send pages back to you.
Public vs private IP
Your router gives each device a private IP (like 192.168.1.5) at home. The internet only sees one public IP for your whole house.
Page range
A way to choose pages: 1-3 means pages 1 to 3; 5 means only page 5; 7- means page 7 to the end.
