What is IANA domain?
The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol-related symbols and Internet numbers.
What are the three different types of port number ranges as defined by IANA?
The port numbers are divided into three ranges: the well-known ports, the registered ports, and the dynamic or private ports.
What is the highest registered port?
65,535
The highest TCP port number is 65,535. The TCP protocol provides 16 bits for the port number, and this is interpreted as an unsigned integer; all values are valid, apart from 0, and so the largest port number is (2^16 – 1) or 65,535.
What is the standard IANA port number used for requesting web pages?
User port numbers range between 1024 and 49151. If you wish to register a system port — those numbered 1023 or less — it must be done through the standardisation process of the IETF.
What is the range for registered ports?
1,024 – 49,151
The registered ports are those from 1,024 – 49,151. DCCP registered ports should not be used without IANA registration. The registration procedure is defined in document RFC4340, section 19.9. The dynamic and/or private ports are those from 49,152 – 65,535.
What is the function of IANA?
IANA, the Internet Assigned Numbers Authority, is an administrative function of the Internet that keeps track of IP addresses, domain names, and protocol parameter identifiers that are used by Internet standards.
What are the top level domain names?
A top-level domain ( TLD ) is the part of the domain name located to the right of the dot (” . “). The most common TLDs are .com, .net, and .org.
What are examples of top level domains?
Top-level domain ( TLD ) refers to the last segment of a domain name, or the part that follows immediately after the “dot” symbol. TLDs are mainly classified into two categories: generic TLDs and country-specific TLDs. Examples of some of the popular TLDs include .com, .org, .net, .gov, .biz and .edu.
