What is an IP Address?

The internet is connected via an internet protocol, often abbreviated as IP Address. It refers to the location of your website’s files, which is called a server. There are records of your website’s data passed around by your Domain Name Server.

The internet protocol is broken most commonly into Internet Protocol version 4 and version 6. Since IPv4 has been around for longer, this is the standard most users will be familiar with seeing.

What is IPv4?

The internet protocol version 4, often abbreviated as IPv4, is the most common and easily identifiable IP address. It is a 32-bit address that includes 4,294,967,296 different addresses in total. However, some restrictions apply for specific networking purposes.

The values range from to, with the most known IP address being This private IP address is in use by Netgear and D-Link Local Routers, which is commonplace in most households.

What is IPv6?

The new internet protocol version 6, often abbreviated as IPv6, is less known than its predecessor. It is a 128-bit address that includes 340,282,366,920,938,463,463,374,607,431,768,211,456 different addresses in total.

This protocol was introduced to deal with the increasing demands on IPv4. However, despite being completed, not many internet service providers have updated their infrastructure to accommodate to this standard. Having both an IPv4 and IPv6 address is common, but the IPv6 address is optional.

Which is better for SEO, IPv4 or IPv6?

In short, both IPv4 and IPv6 are excellent for search engine optimisation. However, due to the current state of the internet’s infrastructure, you will most commonly use IPv4 addresses for your computer.

There is a compelling argument to be made that the adoption of IPv6 will change Google’s algorithm. Since IPv4 addresses are exhausted, specific footprints and best practices have emerged. With the introduction of IPv6, these may evolve.

For example, a type of link building that uses IP manipulation is called Private Blog Networks.
