Fully Qualified Domain Address

A fully qualified domain address (FQDA) is a string forming an Internet e-mail address. It was defined by the Internet Engineering Task Force in RFC 3801 for the use in voice profiles for Internet mail, but has been used on the Internet as early as 1988.

A FQDA is composed of a local part, followed by the symbol @ and the fully qualified domain name (FQDN) of the host responsible for a mailbox.

An example of a FQDA is: localpart@mailhost.example.com. The local part usually denotes a username, while the fully qualified domain name is used by mail transfer agents to determine the IP address of the host by querying the Domain Name System.

Famous quotes containing the words address, domain, fully and/or qualified:

    There’s nothing that makes you so aware of the improvisation of human existence as a song unfinished. Or an old address book.
    Carson McCullers (1917–1967)

    In the domain of art there is no light without heat.
    Victor Hugo (1802–1885)

    Lay down, lay down the bigly bier,
    Lat me the dead look on;
    Wi’ cherry cheeks and ruby lips
    She lay an’ smil’d on him.

    O ae sheave o’ your bread, true-love,
    An’ ae glass o’ your wine,
    For I hae fasted for your sake
    These fully day [is] nine.
    Anna Gordon Brown (1747–1810)

    Let’s face it. With the singular exception of breast-feeding, there is nothing about infant care that a mother is innately better qualified to do than a father. Yet we continue to unconsciously perpetuate the myth that men just don’t have what it takes to be true partners in the process.
    Michael K. Meyerhoff (20th century)
