dig.js

Create and capture DNS and mDNS query and response packets to disk as binary and/or JSON. Options are similar to the Unix dig command.

Install

npm install -g 'git+https://git@git.daplie.com/Daplie/dig.js.git#v1'

If you don't have git installed you can also try the npm repo:

npm install -g dig.js

Usage

Format

dig.js [TYPE] <domainname>

Example

dig.js daplie.com

mDNS Browser Example

This is pretty much an mDNS browser

dig.js --mdns _services._dns-sd._udp.local

Really the --mdns option is just an alias for setting all of these options as the default:

dig.js -p 5353 @224.0.0.251 PTR _services._dns-sd._udp.local

Moar Examples

dig.js A daplie.com

dig.js -t A daplie.com

dig.js @8.8.8.8 A daplie.com

Options

--debug
--mdns
--output <path/to/file>     write query and response(s) to disk with this path prefix (ex: ./samples/dns)
-t <type> (superfluous)     default ANY (mdns default: PTR)
-c <class>                  default IN
-p <port>                   default 53 (mdns default: 5353) (listener is random for DNS and 5353 for mDNS)
-q <query> (superfluous)    required (ex: daplie.com)
