An IP address is, for an Internet Protocol address, an identification number for network hardware connected to the network. Having an IP address allows a device to communicate with other devices on an IP-based network such as the Internet (IPv4 vs IPv6).


An IP address is a binary number, but it can be stored as text for individual readers. For example, a 32-bit numeric address (IPv4) is written in decimal as separate numbers by four numbers. Each number can be from zero to 255 … IPv6 addresses are 128-bit IP addresses written in hexadecimal and separated by colons.

what is an IP address used for?

Yes, of course, an ID can be detected with ease as if an IP address provides an identity to a network device on the Internet. Similar to a home or business address considering a specific physical location with an identity address, and devices on the network differ from each other by IP addresses. (IPv4 vs IPv6)

If you send a package to a friend in another country, you must know the exact destination. This common procedure is used to send data over the Internet. However, instead of using a physical mailing address, the computer uses a DNS server to look up the hostname to find its IP address.

For example, when you enter a website URL such as in a browser, your request to load that page is sent to the DNS servers who view it to find their corresponding IP address life wire .com’s hostname. Without an IP address, the computer has no clue what it is that you’re after.

IP version (IPv4 vs IPv6)

There are two versions of IP: Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). The former is the older version, while IPv6 is the enhanced IP version.


One reason for IPv6 replacing IPv6 is that it provides a larger number of IP addresses than IPv4. When multiple devices on the same network are connected to the Internet, it is important that a unique address is available for each device. (IPv4 vs IPv6)

.IPv4: The way IPv4 addresses are created means that it is capable of providing more than 4 billion unique IP addresses (232). Although it has a large number of addresses, it is not enough for the modern world with all the various devices used on the Internet.


IPv6: IPv6 supports 340 trillion, trillion, trillion addresses (2128). That’s 340 with 12 zeros! This means that every person on Earth can connect billions of devices to the Internet.


Imagining this helps to understand how many IP addresses allow IP6 IP6 addressing over IPv6. The page postage stamp can provide enough space to hold each IPv4 address. IPv6, then, at scale, would require the entire solar system to include all of its addresses.

Features of IPv4 vs IPv6

* Connectionless protocol.


* Allow creating a simple virtual communication layer on multiple devices.


* This requires less memory, and easier to remember addresses.


* Protocols already supported by millions of devices


Provides video library and conferences.


* Hierarchical Address and Infrastructure.


Stateful and stateless configuration.


Support for Quality of Service (QoS).


An ideal protocol for neighbour node interactions.

IP for mac resolution: –

* Broadcast ARP.


* Multicast Neighbor Solicitation.


* Local subnet group management.


* Internet Group Management Protocol GMP)


* Multicast Listener Discovery (MLD)


* Optional fields: –


There is an optional field, also, and not an optional field. But extension headers are available.


* Internet Protocol Security (IPSec) is optionally related to network security.


* Internet Protocol Security (IPSec) is mandatory regarding network security.


* Dynamic Host Configuration Server: – Whenever they want to connect to a network, customers have DHCS (Dynamic Host Configuration Server).


Clients do not have to contact any such servers as they are given permanent addresses.

Mapping: –

* Uses ARP (Address Resolution Protocol) to map MAC addresses


* Uses NDP (Neighbor Discovery Protocol) to move to MAC addresses.


1023 me with mobile devices

IPv4 address uses dot-decimal notation. Therefore it is not suitable for mobile networks.


 IPv6 addresses are represented in hexadecimal, colon-separated notation. IPv6 is better suited for mobile networks.


IPv4 vs IPv6 cannot communicate with others but can exist simultaneously on the same network. This is known as dual-stack.

Benefits of IPv6

One of the most frequently asked addresses about the benefits of IPv6 is increasing the pool, IPv6 has other important technological changes that will improve the IP protocol.


No more NAT (network address translation)


. Auto-configuration.


. No more private address conflicts.


. Better multicast routing.


. Simple header format.


. Simplified, more efficient route.


. True Quality of Service (QoS), also known as “flow labelling”.


. Built-in authentication and privacy support


. Flexible options and extensions.


. Easy Administration (Say Goodbye to DHCP)

 Conclusion: –

An Internet Protocol address is also known as an IP address. (IPv4 vs IPv6)


. IPv4 was the first version of IP that was deployed for production at ARPANET in 1983.


. IPV6 is the most recent version of the Internet protocol. The Internet Engineer Taskforce started it in early 1994.


. IPV4 allows creating a simple virtual communication layer on a variety of devices.


. IPV6 supports hierarchical address and routing infrastructure.


. IPv4 is a 32-bit IP address, while IPv6 is a 128 Bit IP address.


. IPv4 provides five different classes of IP addresses.


. IPv6 128 bit IP address.
