    The Domain Name System specifies a database of information
    elements for network resources. The types of information
    elements are categorized and organized with a list of DNS
    record types, the resource records (RRs). Each record has a
    name, a type, an expiration time (time to live), and
    type-specific data.

    The following is a list of terms used in this program:
    ----------------------------------------------------------------
    | Vocabulary | Description                                     |
    ----------------------------------------------------------------
    | zone       | A DNS zone is a specific portion of the DNS     |
    |            | namespace in the Domain Name System (DNS),      |
    |            | which a specific organization or administrator  |
    |            | manages.                                        |
    ----------------------------------------------------------------
    | name       | In the Internet, a domain name is a string that |
    |            | identifies a realm of administrative autonomy,  |
    |            | authority or control. Domain names are often    |
    |            | used to identify services provided through the  |
    |            | Internet, such as websites, email services and  |
    |            | more.                                           |
    ----------------------------------------------------------------
    | rtype      | A record type indicates the format of the data  |
    |            | and it gives a hint of its intended use. For    |
    |            | example, the A record is used to translate from |
    |            | a domain name to an IPv4 address, the NS record |
    |            | lists which name servers can answer lookups on  |
    |            | a DNS zone, and the MX record specifies the     |
    |            | mail server used to handle mail for a domain    |
    |            | specified in an e-mail address.                 |
    ----------------------------------------------------------------
    | data       | A records data is of type-specific relevance,   |
    |            | such as the IP address for address records, or  |
    |            | the priority and hostname for MX records.       |
