what is ipv4 and ipv6 in computer networks
The IP address allows various devices to communicate with each other via the internet. Every device has own IP address. An IP address like a home address that is unique for every device like a computer, mobiles, etc. IP4 and IP6 are both different terms, we will know about IPv4 vs IPv6 in this articles.
What’s IP?
An Internet Protocol address, also we are known as an IP address. It’s a numerical address like our home address that is assigned to each system related to a pc community which makes use of the IP address for communication. Every system has own unique IP address.
IP address act as an identity for every machine on a selected community. The IP
What is IPv4?
IPv4 was the first version of IP or the internet protocol. It was deployed by ARPANET in 1983. Today every country and service used the IPv4 version. It is used to identify every device on any network using an internet protocol addressing system.
The IPv4 uses a 32-bit security address system that means 2^32 addresses which are more than 4 billion addresses. To date, it is considered the primary Internet Protocol and carries 94% of Internet traffic used IPv4 on the web.
Advantages of IPv4
- Connectionless Protocol
- IPv4 makes data to be secured with encryption
- Permit making an easy digital communication layer over diversified gadgets
- It requires much less reminiscence and ease of remembering addresses
- Already supported protocol by thousands and thousands of gadgets
- Gives video libraries and conferences
What is IPv6?
It was launched in 1994 which is a newer version of the IPv4. Many of the web services still use IPv4 over IPv6.
Each pc, cell phone, residence automation element, IoT sensor and every other gadget related to the Web wants a numerical IP tackle to speak between different units. The unique IP tackle scheme, referred to as IPv4, is working out of addresses as a result of its widespread utilization from the proliferation of so many related units.
Advantage of IPv6
- Stateful and Stateless configuration
- Help for the high quality of service (QoS)
- A perfect protocol for neighboring node interplay
- Simplified Network Configuration
- Security ? IPSec security, which gives confidentiality, authentication, and information integrity, into the IPv6.
- Auto-configuration
ipv4 vs ipv6- Which is faster
I found the test on the Sucuri blog about the speed of the IP address.
So in this test, we see IPv4 is faster than IPv6 according to the Sucuri Blog.
The Difference Between IPv4 vs IPv6?
IPv4 used a 32-bit method for its IP or Internet addresses. Where IPv6 used a 128-bit method for its IP address.
So 32-bit means it can provide support for 2^32 IP addresses is around 4.29 billion. That’s why most of the new services use IPv6 over IPv6.
IPv6 makes used 128-bit security of Web addresses.So it has 2^128 Web addresses=340,282,366,920,938,463,463,374,607,431,768,211,456. The number of IPv6 addresses is 1028 times bigger than IPv4 addresses. So there are greater than sufficient IPv6 addresses to permit Web gadgets to broaden for a really very long time.
IPv4 is using numeric addressing method whereas IPv6 is an alphanumeric addressing method. For Example, IPv4 is like 108.78.629.97 where IPv6 is like 2011:vg87:0000:0000:0000:ff00:0062:7572
Why new services Support IPv6? What are the benefits of IPv6?
It is the newer version of the IPv4 and new features introduced in the IPv6. Not only features, we know that every new version comes with Fixed errors and vulnerability than the previous version.
IPv6 has 128-bit features that’s mean more than 1028 times users used this Protocol than IPv4. It functions equally to IPv4 in that it offers the distinctive IP addresses essential for Web-enabled units to communicate.
More Benefits of IPv6
- Auto-configuration
- No more private address that colloid in IPv4
- Better multicast routing
- Simpler header format
- Simplified, more efficient routing
- No. of the header field is 8
- Type of Addresses is Unicast, multicast, and anycast
- In IPv6, the configuration is optional, depending upon on functions that perform by the device
How to Protect your IP address
Why we have to protect IP addresses on the internet? This is an interesting question about the security of the devices.
With the IP address, you can expose on the web and can be monitor on the internet by the hackers, even Government can spy of your activities.
So how you can protect your IP address
The answer is very Simple, VPN. VPN hides your location on the internet and provides you new IP address and also changes your server location.
How to disable IPv6 on Windows, Mac, and Linux
If your device has IPv6, or you can check the IP address by the various tools. After detecting your IP address, you can disable it by the various VPN services like Avast SecureLine VPN.
Here is the Full guide of disabling on Windows, Linux
IPv4 vs. IPv6: Which is more Security
IPv6 was build with extra security in mind. IP Safety (IPSec) is a collection of IETF security protocols for security, authentication, and information integrity, and it?s absolutely built-in into IPv6.
IPv6 is designed for end-to-end encryption. IPv6 comes with IPSec, IPv6 offers two security headers which utilized individually or collectively
IPv4 Security
IPv4 has been considerably up to date through the years, so the distinction between IPv4 and IPv6 security shouldn’t be extraordinary. The identical IPSec in IPv6 is now accessible for IPv4
