After the sixth, any user could not access anything after R2.
The process that hides multiple IP addresses behind a single IP address is called Network Address Translation (NAT). NAT allows multiple devices on a local network to share a single public IP address when accessing the internet. It works by translating the private IP addresses of the devices into the public IP address, managing the connections and ensuring that the correct data is sent back to the appropriate device. This enhances security and conserves the number of public IP addresses needed.

Many companies offer opt in email addresses for their customers. This allows the customers to receive bulk mail for coupons, and information on offers and allows future offers to be sent directly to you email account. Companies such as Jimmy Johns ,Home Depot and various other companies that serve the public and provide services to the public.

Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​ smb
Because the number of public addresses is limited.

A NAT code, or Network Address Translation code, is a numerical identifier used in networking to manage the translation of private IP addresses to a public IP address. This process allows multiple devices on a local network to share a single public IP address for internet access. NAT codes are essential for maintaining security and conserving the limited supply of public IP addresses. They enable devices within a private network to communicate with external networks while keeping internal IP addresses hidden.
All IPv4 IP addresses can be divided into two major groups: global, or public, or external - this group can also be called 'WAN addresses' — those that are used in the Internet, and private, or local, or internal addresses — those that are used in the local network (LAN).
public ip-addresses are used in the Internet (they are registered addresses). private ip-addresses are used in local networks. imagine you have a computer in your local network that has a public ip-address and your PC has simultaneously an Internet connection: if you try to ping this pc you wouldn't be able to tell which computer is replying, the local one or the webserver.
