What is an IPv6 Address?

Internet Protocol Version 6 is the most recent network layer protocol; systems which allow communication to transfer over a network. Although conceptualized in 1998, it only began to replace IPv4 in 2017.

IPv4 is a 32-bit decimal number containing four number strings, each two to three digits, identifying your device and location. A typical IPv4 address appears like this: 192.168.0.1.

If you want to look up your IPv4 address, you can do that here.

The expectation was that by 2010, all variations of unique IPv4 addresses would be in use.
Network In response, a new network layer protocol was created to allow additional unique addresses, and that was the start of IPv6.

IPv6 is a 128-bit address containing eight strings of four digits separated by colons. A typical address looks something like this: 2018:0ab6:84a2:0000:0000:7a2b:0271:7435

Types of IPv6 Address

There are three types of IPv6 address.

  1. Unicast – one-to-one communication, a single source transmitting data to a single destination.
  2. Multicast – one-to-many communication, a transmission received by a group of devices as the destination.
  3. Anycast – similar to multicast, however, the source chooses the closest destination of many for transmission.

Advantaged of IPv6

Advantages include:

  • More available addresses
  • Improved connectivity in p2p networks
  • Faster speeds
  • Auto-configuration
  • Routing efficiency
  • Strong security
  • Higher conversion rates

Disadvantages include:

  • IPv4 remains more popular
  • IPv6 and IPv4 can’t communicate directly and requires a server
  • VPN providers have been unresponsive in upgrading servers to support IPv6

Due to the many advantages of IPv6, the majority of network engineers, data centers, tech companies, and mobile carriers utilize IPv6. IPv6 is the preferred choice for professionals, and it should be for the average user as well.
