Words to know
- BIN / IIN
- The first 6–8 digits of a card. They tell which network (Visa, Mastercard…) and which bank issued it, like an area code on a phone number.
- 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.
- 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.
