# let's dig the server
dig example.com
# from the DNS answer we are interested in the authority section
#;; AUTHORITY SECTION:
#example.com. 79275 IN NS a.iana-servers.net.
#example.com. 79275 IN NS b.iana-servers.net.
# now we find out all subdomains
dig @a.iana-servers.net example.com axfr

#dev.example.com. 1800 IN A 1.2.3.4
#dev2.example.com. 1800 IN A 5.6.7.8
