host

host is a simpler DNS lookup tool than dig. Its output is concise and human-friendly; for scripting or deep debugging, reach for dig.

host example.com                 # A and AAAA records
host -t MX example.com           # a specific record type
host -a example.com              # all records (verbose)
host 93.184.216.34               # reverse lookup

Like dig, it ships with BIND and respects /etc/resolv.conf for default resolvers.
