Do you really need ISP to get access to Internet services?
If you want to access the internet at home, you’ll need an Internet Service Provider (ISP) and a router to connect to the ISP. ISPs often provide a router with their service. This means more than one computer or device in your house can use the broadband connection at the same time.

Why do we need ISP to connect to the Internet?
ISPs allow users access to networks that contain the required equipment, enabling users to establish Internet connectivity. ISPs are responsible for making sure you can access the Internet, routing Internet traffic, resolving domain names, and maintaining the network infrastructure that makes Internet access possible.
Does an ISP need to buy IP addresses?
Yes, ISPs need to buy IP addresses. Packets on the Internet are routed based on IP address. Assume an ISP like verizon, they will have bought some IP addresses and they advertise these range of addresses to the Internet. The number of IP addresses an ISP buys depends on lot of factors.
How does the ISP assign the IP address of a router?
If it is a residential internet account, the ISP usually has a pool of addresses that it allocates from dynamically, so the router will be assigned a dynamic address from that pool using something like DHCP or RADIUS. If it is a business account, the IP address will often be statically assigned (also via DHCP or RADIUS).
Is my ISP connected to all of my other ISPs?
Each ISP is connected to at least one, and probably multiple, other ISP (s). When you send or receive traffic on the Internet, it probably crosses multiple ISPs to reach its destination. It may be that the source or destination of your traffic is on the same ISP you are, but that may be unlikely.
Do ISPs buy IP addresses from IANA?
Yes, ISPs buy IP addresses from Internet Assigned Numbers Authority ( IANA ). The Internet Assigned Numbers Authority delegates Internet resources to the regional Internet registry ( RIR) who, in turn, follow their regional policies to delegate resources to their customers, which include Internet service providers and end-user organizations.
