What do IP addresses look like?

         There are currently two different versions of IP addresses in use—IPv4 and IPv6. The two versions look quite different from one another. IP addresses are actually just long strings of numbers, like 3221226037, but to make it easier for people to read them, we write them down in a special way. IPv4 addresses are written as a string of four numbers between 0 and 255, separated by dots. A typical IPv4 address looks like this: 192.0.2.53. IPv6 addresses are considerably longer strings of numbers, so they are written using hexadecimals, which can fit more information into fewer digits. Colons separate the segments of IPv6 addresses instead of dots; for example, 2001:0db8::53. In fact, when you see two colons side by side in an IPv6 address, you know that all the segments between them contain only zeros. Without those colons, The example  address expands to its fully-written version, 2001:0db8:0000:0000:0000:0000:0000:0053.
