What You'll Learn
IP Addressing is a fundamental topic in the CompTIA Network+ exam, as it covers the essential concepts of how devices communicate on a network using Internet Protocol (IP) addresses. Understanding IP addressing is crucial for network professionals to configure, troubleshoot, and maintain network connectivity. This topic explores the different IP address classes, subnet masking, and the use of public and private IP addresses, all of which are critical knowledge areas for the Network+ certification.
Key Concepts
IPv4 Address Structure
An IPv4 address is a 32-bit number typically represented in dotted-decimal notation (e.g., 192.168.1.100). It consists of a network portion and a host portion, which are determined by the subnet mask.
IP Address Classes
IPv4 addresses are divided into five classes (A, B, C, D, and E) based on the network portion of the address. Each class has a different default subnet mask and range of available IP addresses.
Subnet Masking
A subnet mask is a 32-bit number used to divide an IP network into smaller subnetworks (subnets). It determines the network and host portions of an IP address, allowing for more efficient use of IP addresses.
Private and Public IP Addresses
Private IP addresses are used within a local network and are not routable on the internet. Public IP addresses are used to communicate on the internet and are assigned by Internet Service Providers (ISPs).
CIDR Notation
Classless Inter-Domain Routing (CIDR) notation is a way to represent an IP address and its subnet mask using a single value, such as 192.168.1.0/24, where the /24 represents the subnet mask.
Common Mistakes to Avoid
- Confusing the network and host portions of an IP address
- Incorrectly calculating the number of available IP addresses in a subnet
- Failing to understand the differences between private and public IP addresses
- Misunderstanding the purpose and use of subnet masks
- Struggling to convert between dotted-decimal and binary representations of IP addresses
