Why use arp and traceroute?

arp and traceroute are both network diagnostic tools used for different purposes:

arp

• Purpose: The Address Resolution Protocol (ARP) is used to map IP addresses to MAC (Media Access Control) addresses in a local network.
• Usage: It helps in identifying the hardware address of a device when you know its IP address. This is essential for communication within a local network.

traceroute

• Purpose: traceroute is used to trace the path that packets take from your computer to a destination host across a network.
• Usage: It shows the route taken by packets and the time taken for each hop, which helps in diagnosing network issues, identifying bottlenecks, and understanding the network topology.

Both tools are valuable for network troubleshooting and management.
