IP addresses

DéfinitionAdresses IP

An IP address is a number that identify a machine.

Every machine connected to the Internet has an IP address.

  • IPv4, example

  • IPv6, example : 2001:0db8:0000:85a3:0000:0000:ac1f:8001

AttentionStatic or dynamic IP

An IP address can be static or dynamic:

  • only machines with static IP can work as servers

  • other machines are content consumers only (example : the smartphones)

ComplémentIPv4 shortage

Most of the IPv4 addresses are already in use and IPv6 is still not implemented by major actors.

This creates a shortage of static addresses.
