IP Addresses and Network Representation

Front

What is an IP Address?

Back

An IP Address (Internet Protocol Address) is a unique identifier assigned to each device connected to a network that uses the Internet Protocol for communication.

Front

What are the two main types of IP Addresses?

Back

The two main types of IP Addresses are IPv4 (32-bit) and IPv6 (128-bit).

Front

What does IPv4 stand for?

Back

IPv4 stands for Internet Protocol version 4, which uses a 32-bit address scheme allowing for over 4 billion unique addresses.

Front

What does IPv6 stand for?

Back

IPv6 stands for Internet Protocol version 6, which uses a 128-bit address scheme allowing for a vastly larger number of unique addresses.

Front

What is a subnet mask?

Back

A subnet mask is a 32-bit number that divides an IP address into network and host portions, helping to determine which part of the address refers to the network and which part refers to the device.

Front

What is the purpose of a default gateway?

Back

A default gateway is a node (usually a router) that serves as an access point to another network, allowing devices on a local network to communicate with devices on other networks.

Front

What is a MAC address?

Back

A MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications at the data link layer of a network.

Front

What is the difference between public and private IP addresses?

Back

Public IP addresses are assigned to devices that are directly connected to the internet, while private IP addresses are used within a private network and are not routable on the internet.

Front

What is NAT (Network Address Translation)?

Back

NAT is a method used to translate private IP addresses to a public IP address, allowing multiple devices on a local network to share a single public IP address.

Front

What is a DNS (Domain Name System)?

Back

DNS is a system that translates human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network.
