Which of the following is not available in URL?

The correct answer is IP address.

Key Points

• A URL (Uniform Resource Locator) is a reference to a web resource, and it specifies its location on a computer network.
• The main components of a URL are the protocol (e.g., HTTP, HTTPS), domain name (e.g., www.example.com), and optionally the file name or path (e.g., /index.html).
• IP address is not included in a URL directly; instead, the domain name is translated into an IP address through the Domain Name System (DNS).
• For example, the URL "https://www.example.com/index.html" comprises the protocol (https), domain name (www.example.com), and file name (index.html).
• The protocol defines the rules for communication, while the domain name provides a human-readable address for accessing the server hosting the resource.

Additional Information

• Domain Name System (DNS):
  • The DNS translates human-readable domain names (e.g., www.google.com) into numerical IP addresses (e.g., 172.217.14.238).
  • It serves as a directory for the internet, simplifying navigation for users.
• IP Address:
  • An IP address is a unique identifier for a device on a network.
  • It comes in two versions: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
• Protocol:
  • Protocols such as HTTP, HTTPS, FTP, and SMTP define rules for data exchange over the internet.
  • HTTPS (Hypertext Transfer Protocol Secure) ensures encrypted communication for secure web browsing.
• File Name:
  • The file name or path in a URL identifies the specific resource or file on the server.
  • For example, in "https://www.example.com/index.html," "index.html" is the file name.
