Compare with:

subdomains(tld_length = 1)

Returns all the \subdomains as an array, so ["dev", "www"] would be returned for “dev.www.rubyonrails.org”. You can specify a different tld_length, such as 2 to catch ["www"] instead of ["www", "rubyonrails"] in “www.rubyonrails.co.uk”.

Parameters

tld_length opt = 1
