"Dig" is a tool on Unix and Linux servers that queries the Domain Name System for DNS records.

=== About the Dig tool ===
Computers use the Domain Name System (or DNS for short) to convert human-readable domain names (e.g. www.soliddevtools.com) into an IPv4 address (e.g. '''109.228.50.239''') or an IPv6 address (e.g. '''2a00:da00:1800:15a::1''').

DNS records also store information about the millions of domains and websites that are on the Internet - such as an approved list of servers that can send mail on your domain's behalf (known as SPF records.)

=== Use Cases ===
Use the Dig tool on Solid Tools for Developers to:

* Find the IP address of a website
* Check if a DNS record exists
* Check if a change made in DNS has been published

=== Usage ===
Enter a DNS record you wish to query in the "Domain name/record" field - e.g. '''www.google.com'''.

If you wish to query a specific DNS server, enter it's hostname or IP address in the "DNS server" field. If you don't know what this is, leave it as '''localhost'''.

Select the type of record you would like to query. For example: to find the IP address of a domain name, use the query type '''A (IP address).'''

By default, Solid Tools for Developers will use its own DNS server to return your results. This may include cached data if the record was recently queried. To force the use of "live" data, tick the "Trace" option.

=== Results ===
The complete output from the "Dig" tool will be displayed.

The "flags" line at the top will include a line like '''QUERY: 1, ANSWER: 1, AUTHORITY: 4'''. The figure next to '''ANSWER''' will tell you how many results were found.

The results themselves will be displayed under the section labelled ''';; ANSWER SECTION'''.

The following example shows a successful query to find the IPv4 address of '''www.google.com''':
