Developers skipped IPv5 for the less limited IPv6
This article explains why IPv5 never became an official internet protocall.
What is IPv5?
An internet protocol is the set of rules that govern how information packets are transmitted over a connection.
IPv5 is a version ofInternet Protocol (IP)that was never formally adopted as a standard.
The “v5” stands for version 5 of the Internet Protocol.
Computer networks use version 4, typically calledIPv4, or a newer version: IPv6.
Limitations of IPv5
IPv5 never became an official protocol due to a variety of limitations in it.
What is known as IPv5 started out under a different name: Internet Stream Protocol, or simply ST. ST was effective at transferring data packets on specific frequencies while maintaining communication.
IPv5 used IPv4’s 32-bit addressing, which eventually became a problem.
By 2011, the last remaining blocks of IPv4 addresses were allocated.
With IPv5 using the same 32-bit addressing, it would have suffered from the same limitation.
So, IPv5 was abandoned before ever becoming a standard, and the world moved on to IPv6.
IPv6 is a 128-bit protocol, and it provides more IP addresses.
An example of an IPv6 address is 2001:0db8:0000:0000:1234:0ace:6006:001e.
The format of an IPv6 address is long and often contains numerous zeros.
Leading zeros in the address can be suppressed to shorten addresses.
Only one::symbol can appear in an IPv6 address.
IPv6 was necessary to accommodate the growing number of devices connecting to the internet.
If you still have problems, run Windows Troubleshooter and reset the IPv6 prefs.
