Digging for hosts on FreeBSD 10

FreeBSD 10 now has unbound for DNS lookups, which is actually a lot better than BIND (the zone server, nsd, is not in FreeBSD base), but I was confused when my favourite DNS tooldig(1) was MIA. So, what can we use now?

host(1)

host(1) is usually part of BIND, but for FreeBSD 10 a compatible replacement has been imported from ldns-host.

Code:

[~]% host arp242.net
arp242.net has address 66.111.4.53
arp242.net mail is handled by 20 in2-smtp.messagingengine.com.
arp242.net mail is handled by 10 in1-smtp.messagingengine.com.

It has a nice short output, which is cool. For a reverse lookup, just use the IP address:

Code:

[~]% host 66.111.4.53
53.4.111.66.in-addr.arpa domain name pointer web.messagingengine.com.

Using dig arp242.net NS

Code:

[~]% host -tNS arp242.net
arp242.net name server ns0.transip.net.
arp242.net name server ns2.transip.eu.
arp242.net name server ns1.transip.nl.

dig arp242.net ANY can be done with host -a

Code:

[~]% host -a arp242.net

drill(1)

drill(1) comes with Unbound, and behaves a bit more like dig.

Code:

[~]% drill arp242.net

Reverse lookup with -x:

Code:

[~]% drill -x 66.111.4.53

And classes work like dig as well.
