This what an IPv6 address looks like: 2600:1005:b062:61e4:74d7:f292:802c:fbfd
You are probably more familiar with IPv4 addresses which look like this: 75.123.253.255
IPv6 is the future, and in the fullness of time IPv4 will most likely be phased out.
I am toying with the notion of switching to IPv6 but before I do has anyone here already done so and are there any advantages or disadvantages?
