What are the differences between ARP, DHCP, and DNS?

What Is ARP

What is ARP?

ARP is the abbreviation of Address Resolution Protocol.

Now, you might continue to read this post fromMiniToolto get more information about ARP.

Without ARP, the host will not be able to find the hardware address of another host.

How Does ARP Work

How does ARP work?

The data packet arrives at the gateway, and the destination is a specific host.

The ARP cache records each IP address and its matching MAC address.

The ARP cache is stored on all operating systems in the IPv4 Ethernet data pipe.

If it exists, no new request is required.

Types of ARP

ARP has different types.

Now, lets see the details about the types of Address Resolution Protocol.

Proxy ARP

The first key in of ARP is proxy ARP.

The proxy knows the location of the traffic destination and provides its own MAC address as the destination.

Gratuitous ARP

The second key in of ARP is Gratuitous ARP.

An ARP request that converts an IP address to a MAC address will not prompt for gratuitous ARP.

Reverse ARP (RARP)

The third key in of ARP is RARP.

Hosts that do not know their IP address can be discovered using Reverse Address Resolution Protocol (RARP).

Inverse ARP (IARP)

The last jot down of ARP is IARP.

Now, here is all information about types of ARP.

ARP is the process of connecting a dynamic IP address to the MAC address of a physical machine.

As mentioned earlier, IP addresses are designed to be constantly changing for a simple reason.

Doing so provides users with security and privacy.

However, the IP address should not be completely random.

There should be rules for assigning IP addresses from a defined range available in a particular web connection.

This helps prevent problems, such as two computers receiving the same IP address.

These rules are calledDHCP(Dynamic Host Configuration Protocol).

When you search for domain names or uniform resource locators (URLs), they use alphabetic names.

On the other hand, computers use numeric IP addresses to associate domain names with servers.

Final Words

Now, its time to make a conclusion.

you might know the definition, importance, work principle, as well as the types of ARP.

Besdies, you could know the differences between ARP, DHCP, and DNS.

I hope that this post can be helpful to you.
