Assignment	Assigned by DHCP or manually	Assigned by manufacturer

Introduction

When it comes to networking and communication, two key identifiers are IP (Internet Protocol) and Mac (Media Access Control) addresses. Both play crucial roles in ensuring data packets are routed correctly and devices can communicate effectively on a network. While they serve similar purposes, there are distinct differences between the attributes of IP and Mac addresses.

Structure

IP addresses are logical addresses assigned to devices on a network. They are used for routing data packets across networks and are essential for devices to communicate with each other. Mac addresses, on the other hand, are physical addresses embedded in network interface cards (NICs) and are used to uniquely identify devices on a local network.

Format

IP addresses are typically represented in a dotted decimal format, such as 192.168.1.1, where each octet ranges from 0 to 255. This format allows for easy readability and understanding of the network hierarchy. Mac addresses, on the other hand, are represented in hexadecimal format, such as 00:1A:2B:3C:4D:5E, with each pair of characters representing a different part of the address.

Assignment

IP addresses are assigned dynamically or statically, depending on the network configuration. Dynamic IP addresses are assigned by a DHCP (Dynamic Host Configuration Protocol) server and can change over time, while static IP addresses are manually configured and remain constant. Mac addresses, on the other hand, are hard-coded into the NIC by the manufacturer and do not change throughout the device's lifetime.

Scope

IP addresses have a broader scope and are used for routing data packets across different networks. They are essential for devices to communicate with each other regardless of their physical location. Mac addresses, on the other hand, have a limited scope and are only used for communication within the same local network segment.

Functionality

IP addresses are used for logical addressing and routing at the network layer of the OSI model. They enable devices to communicate across different networks by providing a unique identifier for each device. Mac addresses, on the other hand, operate at the data link layer of the OSI model and are used for identifying devices on the same local network segment.

Security

IP addresses can be spoofed or changed by malicious actors to disguise their identity or location. This can lead to security vulnerabilities and make it difficult to track the source of network attacks. Mac addresses, on the other hand, are harder to spoof as they are hard-coded into the NIC and cannot be easily changed, providing an additional layer of security for network communication.

Conclusion

In conclusion, IP and Mac addresses play distinct but complementary roles in networking and communication. While IP addresses are essential for routing data packets across networks and enabling devices to communicate with each other, Mac addresses provide a unique identifier for devices on the same local network segment. Understanding the attributes and differences between IP and Mac addresses is crucial for network administrators and IT professionals to ensure efficient and secure communication on a network.
