Global Query Options

A global set of query options, which is applied to all queries, can precede the ﬁrst set of options, name,

query type, query class, and query options supplied on the command line. Any global query options (except

the +[no]cmd query option) can be overridden by a query-speciﬁc set of query options. See Example 5 in

EXAMPLES.

EXAMPLES

Example 1

To look up information about domain

a.example.com

using DNS-Server 10.53.0.2 asking for host

address

A records:

$ dig +tcp +noadd +nosea +nostat +noquest +nocmd -p 5300 \

a.example.com @10.53.0.2 a

Example 2

To query a.example.com

using DNS-Server 10.53.0.2 without authentication, asking for

A records:

$ dig +tcp +noadd +nosea +nostat +noquest +nocmd +noauth \

-p 5300 a.example.com @10.53.0.2 a

Example 3

To request a transfer:

$ dig +tcp +noadd +nosea +nostat +noquest +nocomm +nocmd \

example.com @10.53.0.2 axfr -p 5300

Example 4

To request a transfer with Transaction Signature (TSIG):

$ dig +dnssec +tcp +noadd +nosea +nostat +noquest +nocomm +nocmd \

tsigzone.com @10.53.0.3 axfr -y tsigzone.com:1234abcd8765 -p 5300

The key is 1234abcd8765 .

To secure server-to-server communication, BIND 9 primarily uses TSIG for zone transfer, notify, and recur-

sive query messages. TSIG is very useful for dynamic updates.

Example 5

To make three lookups from the command line:

$ dig +qr www.bind.org any -x 127.0.0.1 bind.org ns +noqr

The three queries are:

www.bind.org any An ANY query for domain name www.bind.org .

-x 127.0.0.1 A reverse lookup of 127.0.0.1

bind.org ns +noqr A name server lookup for domain bind.org, suppressing the query

display for this query only (+noqr).
