A Fully Qualified Domain Name (FQDN), sometimes also referred to as an absolute domain name, is a domain name that specifies its exact location in the tree hierarchy of the Domain Name System (DNS). It specifies all domain levels, including the top-level domain and the root zone. A fully qualified domain name is distinguished by its lack of ambiguity: it can only be interpreted in one way. The DNS root domain is unnamed, which is expressed by the empty label, resulting in an FQDN ending with the dot character.

From this screen, you can Add or Modify an FQDN. You can also filter the FQDNs based on FQDN Name or IP Address using the filter text box.

Filter By Name

By default, radio button for FQDN Name is selected and when you enter any FDQN Name in the search text box, it displays the results for related FQDN entries.

Filter By IP

If you select the radio button for FQDN IP and enter any FQDN IP in the search text box, it displays the results for FQDN entries which have a related IP address.

If you enter any text in the filter text box that is contained in the name/IP, the list will be instantly filtered to show the matching results. If you enter some text in the filter text box that is not in any name/IP (depending on the radio button selected) the text box flashes red and the text that does not match is deleted.

In the FQDN table, you can sort the FQDN entries available for FQDN Name, IP Address, and Availability options using up/down arrow on FQDN table header.

  • For FQDN Name, entries can be sorted in alphabetical order or reverse alphabetical order.

  • For IP Address, entries can be sorted first by IP version (IPv4 followed by IPv6), then by IP address or reverse alphabetical order.

  • For Availability, entries are sorted by the Down status first, followed by the remaining FQDNs only when there are Up and Down status FQDNs available in the list. If there are multiple FQDNs present in the list with multiple statuses like Up, Down, Disabled, and Unconfigured then sorting occurs in the following order:

    • Unconfigured

    • Disabled

    • Down

    • Up

    In reverse order:

    • Up

    • Down

    • Disabled

    • Unconfigured
