IP stand for Internet Protocol, It is an specefic address to identifying number for a piece of network
Having an IP address allows a device to communicate with other devices over an IP-based network like the internet.
Most IP addresses look like this:
Other IP address you might come across could look more like this:
There’s a lot more on what those differences mean in the IP Versions (IPv4 vs IPv6).
IPv4 v/s IPv6
IPv6 usage has been growing very slowly through the last 10 to 15 years. Since mid-2015 it started to pick up and increase adoption at a rapid pace. Google, for example, has been tracking their IPv6 usage since 2009 and it is beautiful to finally see some growth.
As the number of available IPv4 address continues to go down, we expect to see more of IPv6 very soon. However, one of the main concerns I hear from people is about website speed and perfomance using IPv6 compared to IPv4. A few peopme say its id fastest, since it is less used and has simplified routing. Other people say it is slower with fewer routers and hopes supporting it.
