What is RFC 1918 ?
RFC 1918 is a group of IP addresses also referred to as Private IPs or networks; it means that they are meant for internal usage. Computers with such IP can communicate with each other on a LAN or a network but can not have direct connection to the internet.
Examples of such IP addresses are
10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
Why is it important?
Because there will be a shortage of IPs if every computer worldwide is given a distinct IP address.
It also adds some privacy to the internet because they are for internal use meaning people outside your network will not be able to access them without the help of a gateway device adding some security.
Normally a NAT (Network Address Translation) is configured so that private IPs can connect to the internet. Routers and other gateway devices also bring the private network and internet together.
Hope this helps ??

Request for Comment (RFC) 1918 describes the methods for address allocation on a private network.

Private IP space allocation.

It allows you to place a large number of hosts behind a NAT firewall, isolated from the Internet. This alleviates the pressure on the limited public IP space.
