Briefly explain what the command host does.
What will be an ideal response?
host is a simple utility for performing DNS lookups. It is normally used to convert names to IP addresses and vice versa. It can also be used to:
? display the SOA records for zone name from all the listed authoritative name servers for that zone. The list of name servers is defined by the NS records that are found for the zone.
? make a DNS query of a particular class. The default class is IN (Internet).
? perform a zone transfer for a particular zone. This option is equivalent to making a query of type AXFR.
? specify that reverse lookups of IPv6 addresses should use the IP6.INT domain and nibble labels as defined in RFC1886. The default is to use IP6.ARPA and binary labels as defined in RFC2874.
? select the query type from any of the CNAME, NS, SOA, SIG, KEY, AXFR, etc.
? make non-recursive queries
