An IP address basically points to a computer, whether it is the physical hardware or a virtual one as in the case of shared hosting. In comparison, a typical URL contains the protocol to be used i. It is obvious to see that an IP address can be part of a URL, although it is more common to see a domain name instead of an IP address.
Without the DNS, the request would fail as the computer would not be able to find the host. One thing that the internet is facing right now is the rapid depletion of the IP address pool due to the rapid growth of the internet. That is why IPv6 was developed to increase the maximum number of IP addresses that can be used. On the other hand, there is virtually no limit to the number of possible URLs because there is no limitation to the name.
It is also very common for larger sites to have multiple URLs point to the same site to ensure that their users are not misled by people who might register the similar domain name. To sum it all up, a URL is a more comprehensive pointer to what you want on the internet and where it is found. An IP address is just the address of the computer. Some computers may have a default behavior when accessed and typing the IP address on a browser would immediately use the HTTP protocol and go to the index page of the site.
An IP address just specifies the location while a URL specifies location, protocol, and specific resource 2.
Thus, the Internet supports the use of a text name that represents one or more IP addresses. A domain name is the text version of an IP address. Figure shows an IP address and its associated domain name. As with an IP address, the components of a domain name are separated by periods.
The text in the domain name up to the first period identifies the type of Internet server. In Figure , for example, the www indicates a Web server. The Internet server portion of a domain name often is not required.
Every domain name contains a top-level domain TLD , which is the last section of the domain name. When you specify a domain name, a server translates the domain name to its associated IP address so that data and information can be routed to the correct computer. This server is an Internet server that usually is associated with an Internet access provider. As described above, IP addresses are represented as an aggregate of four numbers from 0 to , which means that IP addresses can be allocated up to 4,,, computers, which will be running out in the near future.
It simplifies the tracking and routing of calls. The U. Private IP addresses are the IP addresses which can be used only in a particular network. Global IP addresses are the general IP addresses which should be unique in the world. However, the fact that IP addresses are running out cannot be avoided. It seems that the world is starting to finally adopt IPv6. The Internet is essential for business and daily life now.
