90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont    <para><command>Nslookup</command>
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont      is a program to query Internet domain name servers.  <command>Nslookup</command>
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont      has two modes: interactive and non-interactive.  Interactive mode allows
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont      the user to query name servers for information about various hosts and
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont      domains or to print a list of hosts in a domain.  Non-interactive mode
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont      is
90f35c2f2a1c660f3b96eec413036d238df395f6Francis Dupont      used to print just the name and requested information for a host or
c7d32c0b0ff4c01f0d4479af3410d3c06044d48aAutomatic Updater      domain.
