dns: request all host records?

stateless · 01-07-2014, 05:20 PM

Can dig (or some other tool) ask a dns server to give you all A/AAAA records for a zone? Seems like that would be rather handy, but somehow missing it in the manual pages...

Code:

dig @server_ID <name of zone file>

In case a TSIG is required, use -k <path of file containing the TSIG key>

IDK about other validating mechanisms apart from TSIG.

EIDT: that gives the entire zone file; you could post-process the output to get only the record types you want.

Code:

dig @host zone

does only answer the host entries for the specified zone. (in my case, the zone file equales the zone name, so I can't vouch for situation where that would be different.

Code:

dig axfr @host zone

would do a zone transfer though if settings allow (!!), so you can parse indeed as catkin mentions. you'd have to grep for A and AAAA fields.
