ipv6 is the sixth version of Internet Protocol. It’s a group of specifications which come from IETF (Internet Engineering Task Force). The best way to describe ipv6 is an improved version of ipv4.
ipv4 has a lot in common with ipv6. In terms of common ground, both feature tools, including “ping work” for testing of a network, and both allow devices to use the IP versions as sources and destination addresses for passing packets over networks.
ipv6 is the next-gen version which replaces version 4.
Why Is IPv6 Replacing IPv4?
The rationale behind the upgrade from version 4 to version 6 is that demand for new IP addresses is rising. The new version of Internet Protocol, ipv6, is designed to meet the needs of a growing amount of people and hardware. Devices and computers need sender and receiver addresses in order to communicate via the Web. The addresses are numeric and they are called IP (Internet Protocol) addresses.
The sixth version will allow a greater number of devices and users to communicate online because IP addresses will have bigger numbers! With the fourth version, each IP address has thirty-two bits. This equates to a maximum of 4.3 billion addresses which are unique. With the sixth version, ipv6 addresses feature one hundred and twenty-eight bits. This larger bit count allows for around 340 trillion IP addresses which are unique.
In addition to this very important benefit, ipv6 provides supplementary benefits. For example, with ipv6, there is less need for Network Address Tran. As well, apps and computers which are ipv6-enabled will be able to detect services and networks which are ipv6-enabled. This means that the users won’t need to take any action on their own.
Pros and Cons of IPv6
We’ve talked about some “pros” already. Another “pro” is that faster speed will be at your fingertips with ipv6. This is because routing and data flow of the direct type will be better. Also, casual hackers will have a harder time, because there will be so many IP addresses out there. Since speed and security will be positively impacted, this upgrade is definitely a big step forward!
In terms of “cons”, there may be privacy issues to consider. Providers may have set IPs for every person in their networks, and this makes it easier to track people, ban users and give digital data to law enforcement or federal agencies.
While few would argue that the advantages of this sixth version of Internet Protocol outweigh the “cons” dramatically, there is also the risk of system issues. For example, you may need to enable routing for ipv6 quite often, depending on which type of system you’re using. As well, you’ll need to type in an address which is much longer, if the need to type in your IP address manually does arise. It’s pretty easy to make typos when typing in strings of numbers as long as ipv6 addresses!
Now that you have the inside scoop on ipv6, you know what this form of Internet Protocol is, why it was designed and what its benefits and drawbacks are.
